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 the information your business already generates — without forcing the field team to re-enter it.

These are modular capabilities, not a required package. Most engagements begin with one workflow and expand only after it proves its value.

▸ LEAD OPSCall answering, scoring, follow-up cadences, missed-call recovery. Every inbound handled in seconds.
▸ ESTIMATE OPSEstimate drafting from site photos, voice notes, price books and approved business rules — with human review before sending.
▸ 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 OPSPurchase-order drafting and approval, delivery tracking, invoice matching, price-change alerts and recurring-order workflows.
▸ 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. Risks and patterns surfaced for management review — not autonomous project decisions.

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 — DATA HANDLING

Your company’s records end up inside this system. Here is exactly how they are handled.

Most automation vendors selling to contractors never raise this subject at all. It belongs in the architecture conversation, before anything is built — so it is a section on this page rather than a clause you find later.

WHAT ENDS UP INSIDE

Client contracts, employee records, payroll data, financials, project IP, and photos of private property. Operational data about real people and real money — not marketing copy.

WHO CAN SEE WHAT

Role-based access from the first version. The field sees what the field needs; payroll and financials stay with the people who already have that authority. Credentials are separated per service, never shared into one master login.

WHERE IT LIVES

In infrastructure the client controls. Accounts, keys and source code are in your name from day one — so access can be revoked without asking me, and nothing depends on my continued goodwill.

HOW LONG IT IS KEPT

Retention rules are defined during architecture: what is kept, for how long, and what gets deleted on schedule. Recordings and transcripts are treated as the sensitive records they are, not as free storage.

WHAT IS AUDITABLE

An audit trail on the workflows that need one — who approved what, when a record changed, what the system did on its own. If a decision has to be defended later, the evidence exists.

Where formal legal compliance is required, implementation is aligned with the client’s legal counsel. This discipline is not a preference — 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.

04 — 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.

Reliable capture comes first. Automation comes second. That’s the order that survives.

05 — CASES

Five contractor systems. Three that show the engineering depth.

Eight selected examples from 32 systems built — client production work, internal tools and open-source builds. Client engagements are deliberately few: two to three new ones a quarter. The rest of the count is tooling I build for my own delivery and release publicly.

<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.

CONTRACTOR SYSTEMS

Built for contractor and design-build operations — leads, estimates, field reporting, company knowledge and marketing.

CLIENT PRODUCTION · US PROJECT-BASED BUSINESS · NDA PROTECTED

Built for a US project-based business coordinating multilingual employees across active work locations. The system gives field staff a simple way to check in and out, verify location, explain attendance exceptions and submit daily voice reports in their preferred language. Reports are transcribed, structured and normalized into English for management. Managers receive attendance history, exception alerts, project-level visibility, employee and location controls, role-based access and exportable records. A separate read-only ingestion service archives company email and attachments into client-controlled storage, with resumable processing and duplicate protection—creating the foundation for internal knowledge retrieval. The system was deployed in an environment controlled by the client, with operational controls, accounts, source code and documentation handed over.

One-tap field reporting · multilingual voice-to-record processing · client-controlled deployment

Client identity, architecture, business data and project-specific metrics withheld under NDA.

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

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

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

ENGINEERING DEPTH

These are not contractor builds. They are the engineering depth behind the contractor builds — retrieval, multi-agent reasoning and realtime processing, proven where the constraints were harder.

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

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.

07 — 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.

▸ 1-3 WK

Build

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

▸ FINAL

Deploy + own it

Full documentation, source code, credentials — all yours from day one. The system is designed not to depend on me for normal daily operation — ongoing monitoring and improvements stay optional. 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.

08 — 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, voice or a simple mobile action. Minimal new logins and no complex software for the field team to learn.

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 connect the systems worth keeping and create low-friction capture for everything that still happens in calls, messages, notebooks and people’s heads.

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.

09 — WHO BUILDS IT

Vitalii Karasov

HOW YOUR DATA IS HANDLED

Access, ownership and retention are decided during architecture, not after launch. See section 03.

Vitalii Karasov — an AI systems architect and 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 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: private operational systems for owner-led design-build, remodeling and specialty contractor 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.

10 — STRAIGHT ANSWERS

Every question owners actually ask.

The six that come up first. The other 28 are answered in full on one page.

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.

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.

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.

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.

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.

2-4 weeks for most builds. 30-min discovery → 1-2 days architecture (you approve the blueprint before I write a line of code) → 1-3 weeks 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.
