01 — YOU KNOW THESE MORNINGS

“The estimate went out Tuesday. Then nothing. Everyone’s on site — nobody’s job is to follow up.”

“The whole company lives in my head. I take a week off — everything stops.”

A client asks “what fixtures are approved for the master bath?” — and three people spend forty minutes searching emails, drawings and the whiteboard for an answer that was decided six weeks ago.

Materials get ordered over the phone and in a WhatsApp thread. Then nobody knows where the invoice went.

Your projects run late and over budget more often than they should — not because your crew can’t build, but because information falls apart between the field, the office, and the client.

This is what I fix.

02 — WHAT I BUILD

An operational layer that captures, organizes, and retrieves everything your business already knows — without asking anyone to type it in.

▸ LEAD OPSCall answering, scoring, follow-up cadences, missed-call recovery. Every inbound handled in seconds.
▸ ESTIMATE OPSQuote generation from site photos and voice notes, day 2/5/10 follow-up, silent-deal alerts, contract detection in inbox.
▸ PROJECT KNOWLEDGEA searchable brain for every project — blueprints, specs, contracts, emails, RFIs, submittals, meeting notes, photos. Ask in plain English: “what light fixtures are in the master bath?” — answer in three seconds.
▸ FIELD OPSWorker check-in, GPS verification, time tracking, daily reports, material requests, proof-of-work photos, voice notes turned into structured records.
▸ SUPPLIER OPSOrder placement, delivery tracking, invoice reconciliation, price-change monitoring, recurring order automation.
▸ COMMS OPSField-to-office translation. WhatsApp threads, voice notes and SMS parsed into structured records, routed to the right person, logged automatically.
▸ DOCUMENT OPSAutomatic generation of RFIs, submittals, meeting minutes, daily reports, change orders, purchase orders, client updates. You review and approve. The system drafts.
▸ REPORT OPSOwner morning digest, weekly financial rollups, client progress updates, subcontractor performance, labor-hour tracking. Ask any question about your business — get an answer, not a report you have to read.
▸ COMPANY SOPYour standard operating procedures, videos, checklists and drawings — instantly retrievable. “How do we frame a pocket door?” gets an answer with photos and checklist attached.
▸ DECISION SUPPORTSchedule risks, budget risks, recurring project issues, material shortages, productivity trends — surfaced from your own data, not a benchmark report.

VOICE-FIRST WHERE IT MATTERS

Most operational data never gets typed. It lives in phone calls, voice notes, WhatsApp threads, photos on someone’s phone. My systems listen, transcribe, extract, file — so your crew keeps talking the way they already talk, and the office gets structured data on the other side.

03 — SCOPE

Same principles, three depths of engagement.

Some clients start with one broken workflow and stay there. Some start with one and grow into a full company operating layer over 6-18 months. The system is designed to support both.

The foundation is always the same: capture what’s already happening, organize it automatically, make it retrievable, then let the automation grow on top of the data — never the other way around.

Data collection comes first. Automation comes second. That’s the order that survives.

04 — CASES

32 systems built. 7 selected examples below.

Client production systems, internal tools, open-source builds and an award-winning hackathon project.

<5s

Every lead answered and scored — hot ones flagged for an immediate call. The first company to respond wins most jobs.

2·5·10

Day follow-up cadence on every estimate — stops itself the second the client replies. No deal goes quiet unnoticed.

0

Manual CRM upkeep. Every call transcribed, summarized and filed; every email routed. It just stays correct.

CLIENT · PRODUCTION · LA DESIGN-BUILD

Seven connected automations covering intake, qualification, call transcription, follow-up and contract detection. Every inbound lead handled without a single manual touch — every booked call becomes a lead card, every inbound email is read and routed, every sales call is transcribed with a reply drafted, and follow-ups fire on their own until the client replies.

Make.com · ClickUp · OpenAI · Otter · Calendly · Gmail

Inbound leads were falling through the cracks — slow responses, no prioritization, manual copy-paste into spreadsheets. Now hot leads get flagged for an immediate call, warm ones enter a nurture sequence, junk gets filtered out. Speed-to-lead wins jobs: the first company to respond wins most of them.

n8n · Claude API · Google Sheets · REST API

A closed-loop content system: your brand voice, your audience’s pain points and your best-performing posts stored as knowledge; AI drafts platform-ready posts on schedule; engagement data feeds back in, so the system writes better every cycle. Your company stays visible while you run jobs.

Make.com · Claude API · Pinecone · Buffer · RAG

A form-triggered pipeline: five research workflows run in parallel and return a full competitive picture — pricing, positioning, trends — with every claim backed by a real source. Delivered to a spreadsheet and Slack automatically.

n8n · Gemini Deep Research · Airtable · Slack

A client’s team was burning 15+ hours a week on manual research and analysis. I found the bottleneck and replaced it with a pipeline of four specialized AI roles — built and deployed in 5 days.

n8n · Claude API · Supabase pgvector · Webhooks

Every project generates hundreds of photos — progress, finished work, before-and-afters. This tool reads every photo, scores it 1-1000 for quality and picks the keepers automatically — for the portfolio, the client and the marketing folder.

Python · OpenAI Vision · Pillow · rawpy

Not a client build — the engineering depth behind the client systems. A three-layer multi-agent court that audits police bodycam footage, built solo at Europe’s largest AI event. Realtime transcription flags violations in under 2 seconds; a Prosecution agent argues against a Defense agent while a Vision agent reads the video; a Judge issues per-rule verdicts drillable to the exact video frame. A court-defensible audit at ~$0.10–0.20 per recording.

Next.js 16 · FastAPI · Speechmatics · Gemini 3.1 Pro · FAISS

Most client work runs under strict NDA and isn’t shown here — clients don’t want their internal operations public. References available on request.

06 — HOW IT LANDS

Four steps.
No black box.

▸ 30 MIN

Discovery

You describe how jobs come in and where they leak. I ask specific questions. By the end I tell you what’s worth automating, what isn’t, what it costs, and how long. Written scope in 24 hours.

▸ 1-2 D

Architecture

System design before any code. You see the blueprint and approve it. If the architecture is wrong, we fix it on paper — not in production.

▸ 3-7 D

Build

Daily updates. Error handling, monitoring and fallbacks built in from the start. Nothing ships without tests.

▸ FINAL

Deploy + own it

Full documentation, source code, credentials — all yours from day one. The system runs without me. Handoff call walks your team through everything.

For phased platform builds, this same rhythm repeats in 2-4 week increments. Each increment ships something that works before we scope the next one.

07 — YOUR WORLD

I know how your business actually runs.

Your leads come from Google LSA, Angi, Thumbtack, Houzz, Instagram DMs and referrals — and half of them call, not email.

Your crews are in the field with phones, not laptops. Everything works over text or a tap. No logins to forget.

Your data lives in twelve places — Gmail, WhatsApp, spreadsheets, the CRM, QuickBooks, Google Drive, the whiteboard, three notebooks and one office manager’s head. I don’t replace any of them. I connect them.

Your materials get ordered by phone or in a WhatsApp thread. Then nobody knows where the invoice went, or whether the price was right.

Your projects run late and over budget more often than they should — not because your crew can’t build, but because communication falls apart between the field and the office.

Your reality: nobody has time to “learn a new tool.” So there’s nothing to learn. The system runs underneath what you already use.

08 — WHO BUILDS IT

Vitalii Karasov

DATA HANDLING & RESPONSIBILITY

Before AI systems, I ran operations at a humanitarian organization handling personal data of vulnerable populations — under legal and criminal liability for data integrity and privacy compliance. 1.5M+ PLN operational budget, zero audit findings.

For construction and design-build firms, this translates to: client financial data, contracts, employee records and project IP handled with regulated-industry discipline by default. GDPR, PDPL and CCPA compliance mapping included in every build.

Vitalii Karasov — a product manager who builds.

Five years in operations, product and delivery before going full-time on AI systems: EdTech launch, media production, humanitarian crisis logistics with a 1.5M+ PLN budget and zero audit findings. MSc in Strategic Project Management. PRINCE2.

In 2026 my solo build won at the AI Agent Olympics at Milan AI Week — Europe’s largest AI event.

Now I build one thing: the operational layer for construction and home-service companies. Deep, not wide.

The delivery network. On larger builds I bring in trusted specialists — design, development support, QA — but every project stays under my direct scope and my code review. You always know exactly who touched what, and you always talk to me.

09 — STRAIGHT ANSWERS

Every question owners actually ask.

Eight chapters. Open the one that’s on your mind.

Every system I build must save more than it costs — that’s the only rule. For most clients the math is: system cost ÷ average client value = number of clients needed to pay it back. If that number is under ~20 clients or under 6 months for your business, we’re in green territory. If it isn’t, I’ll tell you on the first call and I won’t take the project.

Then the system pays back over more clients and a bit longer — usually 3-6 months instead of 2-4 weeks. The math scales down cleanly. What matters isn’t the size of one job, it’s how many are slipping through your pipeline every month. A 30% lift on a €1,000 average job is the same profit shape as a 30% lift on a $10,000 average job.

Because I don’t build throwaway automations. Everything I ship is documented, monitored, has error handling and fallbacks, and belongs to you fully. A $500 Zapier setup breaks in three months and nobody knows why. I build systems that survive API changes, staff turnover, and a bad Monday.

Systems don’t maintain themselves. OpenAI changes a model, Gmail changes an API, your workflow evolves, edge cases surface. Care Plan means 24/7 monitoring (I know it broke before you do), same-day fixes on business days, monthly improvements as your business changes, and a plain-language monthly report in dollars and jobs saved — not tech jargon.

Standard terms: 50% at signature, 50% at launch. For larger builds we can split into 3 payments across milestones. Care Plan is monthly, cancel anytime. For clients outside the US, I invoice in EUR or USD — your choice.

After the first 30 days I send a plain-language report showing actual saved leads, hours, or errors. If the numbers don’t cover the Care Plan, we adjust the scope or you cancel — no argument. I’ve never had a client where the math didn’t clear within 60 days, but I don’t promise magic and I don’t lock people in.

Full system design, code, integrations, error handling, monitoring dashboards, deployment to your cloud, complete documentation (a real README, not a PDF), 30 days of post-launch support, and a handoff call where I explain every piece. You own the source code, credentials, and infrastructure from day one.

That’s what custom scoping is for. The modules are the common patterns — 80% of clients need 2-3 of them. If yours is different (permits, subcontractor payments, warranty tracking, insurance claims, whatever), we scope it in Discovery and I quote it upfront. Same delivery model, same guarantees.

No. The system runs behind whatever you already have — Gmail, QuickBooks, Buildertrend, JobTread, Housecall Pro, ServiceTitan, Jobber, Google Workspace, Microsoft 365. If a tool I can’t integrate with is central to your workflow, I’ll tell you in Discovery before we sign anything.

Yes — most clients do. Start with 1-2 modules (usually Lead Ops + Estimate Ops), watch the ROI for 30-60 days, layer in the rest as it makes sense. Each additional module is a separate scope and price. No pressure to buy the whole stack upfront.

The core promise is that your team learns nothing new — the system runs underneath what they already use. But if there’s a piece someone needs to touch (approving flagged items, reviewing weekly reports), I record a 5-minute Loom for each and we do one live walkthrough. That’s it.

Every critical action has a human-approval layer by default. Estimates over your threshold, first-time client responses, anything money-related — the AI drafts, you approve, it sends. For low-risk actions (categorizing photos, filing docs, internal summaries) it acts on its own. You choose the line in Discovery.

This is the #1 real risk with LLM systems. I mitigate it three ways: (1) RAG grounding — the AI can only quote from your actual data, not from training memory, (2) DeepEval and grounding checks running in production catch hallucinated outputs before they reach a client, (3) fallback rules that trigger human review when confidence is low. It’s not zero-risk, but it’s engineered risk, not gamble.

Your data stays in your accounts — Gmail, your CRM, your Drive. Where I need a vector database (for company-wide search), it’s deployed to your cloud account (Supabase, GCP, Vultr) — you hold the keys, you can revoke access with one click. No data goes to my servers. No training of external models on your business. Written into every contract.

Care Plan includes 24/7 monitoring. Alerts hit me before they hit your inbox. Same-day fix on business days, next-morning on weekends. Every system has fallbacks built in — usually a “graceful degrade” back to your manual process, so a break rarely means downtime, just temporary manual work while I fix it.

Two layers of coverage. First, my delivery network — the specialists I already work with — can maintain any running system without me for weeks. They know the stack because they helped build it. Second, all systems use standard, well-known tools (LangGraph, Python, Postgres, n8n), fully documented, so any senior engineer can pick things up cleanly. You’re never dependent on my calendar for a system that’s already live.

Cancel Care Plan any month, keep the whole system running. You have the source code, credentials, docs, and cloud access from day one. No lock-in, no ransom fees, no “premium API keys” you have to keep paying me for. If you find someone cheaper to maintain it, hire them — I’ll do the handoff call for free.

Almost never in the first year. It removes the boring 40% of their day (data entry, follow-up chasing, filing) so they can focus on the 60% that actually needs a human (relationships, judgment, exceptions). Most clients keep the same team but stop needing to hire the next one as they grow.

The whole design goal is that they don’t have to. The system runs behind Gmail and their phone. If something needs their attention, it shows up as a normal email or text with two buttons: “approve” or “review”. No dashboards to learn, no logins to remember, no new app on the phone.

Sometimes, if they think it’s about replacing them. That’s why the first thing we do in Discovery is map out what stops being their job (the parts they hated anyway) versus what stays theirs. Clients who introduce it as “this is the tool that makes your job easier” get zero pushback. Clients who introduce it as “AI is replacing headcount” get exactly the pushback they earned.

2-4 weeks for most builds. 30-min discovery → 1-2 days architecture (you approve the blueprint before I write a line of code) → 3-7 days build with daily updates → deployment + handoff. Industry average is 8-16 weeks; I move faster because I don’t do committee reviews and I don’t context-switch across 10 clients.

A 30-45 min call where you describe how jobs come in and where they leak. I ask specific questions, take notes, and by the end I tell you: what’s worth automating, what isn’t, what it would cost, and how long. If we’re not a fit, I say so. If we are, I send a written scope within 24 hours. No pitch deck, no follow-up sales pressure.

Roughly 3-5 hours total across 2-4 weeks. Kickoff call (1 hr), read-throughs of the architecture doc (30 min), 2-3 short check-ins on decisions only you can make (15 min each), UAT before launch (1 hr), handoff (30 min). Everything else runs in the background.

By then the system is stable and you have your first month of numbers. We do a 30-day review call: what’s working, what to improve, what to add next. If you want to continue with Care Plan, we do. If not, you have everything documented and can maintain it yourself or hand it to any developer.

Neither. I’m the senior engineer and product lead on every project — you work with me directly, no account managers, no handoffs. Behind me is a small trusted network of specialists I bring in when a build needs them: a design assistant, a second developer for parallel work, a QA reviewer for critical launches. Upside: senior thinking on every decision, plus enough hands to move fast. Limit: I take 2-3 new engagements per quarter.

Construction firms, design-build studios, home-service companies (HVAC, plumbing, electrical, roofing, landscaping, cleaning, moving), interior designers, remodelers, small commercial contractors. Sweet spot: 5-50 people, owner still involved in day-to-day, average project between €500 and $500K, at least one thing is clearly broken in operations.

I work across US, UAE, and EU timezones with same-business-day response. In 2026-2027 I’ll be spending significant time in Dubai (AI events, Design Week) and Milan (AI Week). If you’re in the Middle East, we can meet in person.

Yes — I’ll share 2-3 depending on which module we’re scoping. Some client work runs under strict NDA and I can only give you screen recordings, not names. If direct references matter to you more than case data, tell me in Discovery and I’ll match you with someone who allows a call.

Big agencies bill $50-500K, take 6-12 months, produce PowerPoints, and rely on junior engineers to actually build. I built the winning system at Milan AI Week solo, in 8 days, against teams that included agency squads. The real proof is that I ship in weeks and it works. Talk to the LA studio running my system for 10,000+ operations.

WhatsApp, LinkedIn, or Telegram — pick your favorite. All three are on my phone, same-day reply. Email works too. My response time in business hours is under 2 hours, worst case next morning in your timezone.

If you’re in Dubai, Milan, Singapore, or anywhere I’m attending an event — yes, glad to. Otherwise everything runs remotely: Loom videos for walkthroughs, WhatsApp for daily updates, Google Meet only when we really need it. Not because remote is trendy, but because it’s faster and clients get more done that way.

Yes. The modules aren’t country-specific. Same lead-to-invoice logic works anywhere — adapted to your CRM, currency, language, and local tools (WhatsApp Business, Bitrix24, Zoho, whatever). Systems have been built for clients across multiple regions and languages.

Yes. Every build includes a data-handling document listing where data lives, who has access, retention rules, and compliance mapping to your applicable regulation (GDPR for EU/UK, PDPL for UAE, CCPA for California, etc.). For heavily regulated industries (healthcare, finance) I bring in a compliance reviewer at cost.

Two options. (1) Book a Discovery call — it’s free, and by the end you’ll have a real scope even if we don’t work together. (2) Ask for a “pilot module” — I build the smallest useful piece for $1,500-3,000 in 5-10 days. If it works, we scale into a full build and credit the pilot against it. If it doesn’t, you have something small that still works and we part on good terms.
