I help early-stage founders make the right technical decisions — architecture, stack, hiring, launch. The questions that quietly cost six to twelve months when you get them wrong.
I'm Aleksandr Protsiuk, founder of Zavod-IT. I started the company in 2011 and over 15 years delivered 200+ products for clients worldwide. Today I work as a fractional CTO for early-stage startups — backed by the same engineering infrastructure I built over the last decade, including 200+ AI coding agents.
Maybe a working demo on Lovable or Replit. Maybe a deck and a deadline. Either way — the next decisions you make are the ones that quietly cost you six to twelve months if you get them wrong.
You don't need a $300K/year CTO to answer these.
You need someone who has answered them 200 times before.
Most founders start with a Consultation or an Audit, then move into an MVP build or fractional retainer once we know what to build.
One hour, one problem, one answer. Bring your specific technical question — stack choice, architecture decision, build vs. buy, hiring strategy, due-diligence prep — and leave with a clear direction.
Your starting point. I review what you have — code, architecture, infrastructure, team — and deliver a roadmap you can act on (or hand to investors).
I build your backend and infrastructure using AI-first development. Same architecture rigor as a traditional team — fraction of the cost and time.
Technical leadership without a full-time hire. I join your team part-time and own the technical direction — including the conversations with engineers, investors, and clients.
Not side projects, not tutorials. 200+ shipped products across SaaS, FinTech, HealthTech, Crypto, Education, and E-commerce.
Python/Django, Node, React, Next.js, Flutter, Postgres, Redis, AWS, GCP. One operator covers the whole stack — no hand-offs, no comms overhead.
Based in Sunnyvale. I meet founders in person when it matters — and I can sit across the table from your investors.
I understand how investors evaluate technology and technical teams — because I've been on the other side of that question.
1st place — Silicon Valley hackathon. Built and shipped under pressure. The same way I work for my clients.
I build with 200+ specialized AI agents daily. Not a gimmick — it's how one operator delivers $100K+ scope at a fraction of the cost.
A framework where specialized AI agents handle different parts of the build — and I architect, review, and orchestrate everything. Every task tracked. Every decision logged. Every line reviewed.
Decides the technology stack, designs the data model, plans API structure. Writes the architecture documents and specs that every other agent works against.
Server-side code — Django, Node, Postgres. APIs, authentication, multi-tenancy, migrations. Multiple agents work different modules in parallel.
Flutter for iOS, Android, macOS. UI implementation, state, API integration, localization across 14+ languages.
React and Next.js — dashboards, admin panels, landing pages. Responsive, accessible, fast.
AWS / GCP infrastructure, Docker, CI/CD pipelines, monitoring, deployment scripts. The plumbing that lets the rest of the system work.
Writes and runs tests. Catches bugs before production. Reviews code against architecture standards.
Marketing strategy, SEO content, social publishing, competitive analysis. Yes — even marketing runs on agents.
Architecting, reviewing, orchestrating. Every deliverable goes through me before it goes to you. The system has a human at the wheel.
Brief, deck, prototype, sketch — whatever you have. We talk it through on a Zoom.
The architecture document, the data model, the task graph. The map the agents work against.
Backend, frontend, mobile — running at the same time, not in sequence. That's where the speed comes from.
Against the architecture. Against the standards. Nothing reaches you without my sign-off.
Documented, tested, deployed, transferable. Not a prototype. Not a "next sprint we'll clean it up." Shipped.
A short sample, grouped by domain. Client names withheld where I don't have permission to share them.
We had a Lovable prototype that looked good in demos but broke with real users. Aleksandr audited the code, gave us a clear roadmap, and rebuilt the backend with his agent system in five weeks. We launched on time.
-- Founder, AI / SaaS startup (Seed)I needed someone who could tell me honestly whether our architecture would survive Series A due diligence. He found three critical issues in the first call and gave us a 90-day fix plan. The investors had zero technical concerns at close.
-- CEO, HealthTech (Series A)What surprised me most was the speed. We went from a product spec to a working MVP with backend, mobile app, and admin panel in six weeks. The same scope was quoted at four months and 3x the price by two agencies.
-- Founder, FinTech startupBook a 30-minute intro call. No pitch, no pressure. Tell me what you're building — I'll tell you if I can help.
