You have an idea
First-time or non-technical founder who wants a senior engineer to own the build — not a marketplace freelancer, not a faceless agency.
Fixed 30-day timeline · Scoped on a call
Your MVP shipped in 30 days
A senior engineer, a dedicated QA, and a project manager build your idea — or rescue your broken vibecoded MVP — and put it in production inside four weeks.
7 years shipping production software
Next.js · TypeScript · Supabase · AI integration
Engineering team based in Europe
Who this is for
If one of these sounds like you, the 30-day model fits.
Your vibecoded MVP is stuck
Cursor, Lovable, Bolt, or v0 got you started. Now auth is broken, deploys fail, or nobody can add features. We untangle it and ship it properly.
You need to ship before the next milestone
Pre-seed or seed founder with a real deadline — demo day, investor check, first paying users. We lock scope and deliver.
What you get after 30 days
A working product in production. Not a prototype, not a demo.
Included
- Production deployment on your custom domain — Vercel, AWS, or self-hosted Coolify on Hetzner if budget is tight. Your call.
- Authentication (email, social, or magic links — your call)
- Database with real data models, not toy seeds
- The core user flow your users actually care about, end to end
- Mobile-responsive UI with dark-mode support
- Basic analytics wired up so you see what's happening from day one
- QA-tested release — regressions caught before they reach you
- Source-code handoff and a short Loom walking you through the architecture
Not included in the 30 days
- Marketing site or long-form landing pages (separate scope)
- Complex payment flows beyond Stripe Checkout / subscriptions
- Ongoing support & maintenance — available on retainer after launch
The 30-day process
One weekly call, daily Slack or Telegram access, full transparency on progress.
Week 1
Scope, shape, design
Kickoff workshop, lock scope, model the data, agree week-by-week deliverables. You sign off before a single line of code ships.
Andrii + PM
Week 2
Build the core
Auth, data models, and the primary user flow come online. End-of-week demo — you click through your product for the first time.
Andrii
Week 3
Build the rest, polish the edges
Secondary flows, error paths, empty states, mobile polish. QA starts regression-testing in parallel.
Andrii + QA
Week 4
Test, deploy, handoff
Full QA sweep, production deployment, documentation, and a one-hour architecture walkthrough.
QA + Andrii
Who does the work
Three humans. No offshore pool, no account managers, no mystery.
Andrii Mazurenko
Senior engineer · owns delivery
7 years shipping production software. Writes the code, makes architecture calls, your direct line on every question.
LinkedIn
Kostiantyn Darmostuk
Project Manager · keeps the 30 days honest
Weekly scope reviews, client-facing updates, and a ruthless 'is this actually in scope?' filter so week 4 doesn't get scary.
LinkedIn
Artem Zaitsev
QA Engineer · catches regressions first
Senior QA with enterprise testing background. Tests every release end-to-end, so 'shipped in 30 days' doesn't mean 'half-broken in 30 days'.
LinkedInBroken MVP? Start here.
Your AI-built MVP doesn't have to stay broken
Lovable, Cursor, Bolt, and v0 can start your MVP. They can't finish it. We take on codebases other agencies refuse to touch — mangled auth, leaked secrets, broken deploys, prompt-sprawled components, no tests — and ship them properly. Same 30-day clock, same team.
Common things we see
- Auth that works in dev and breaks the moment real users show up
- Edge cases that weren't prompted, so they just don't exist
- A production build that refuses to deploy for reasons nobody can explain
- Tangled prompt-generated components the next AI run can't edit cleanly
- Zero tests, so every fix breaks two other things
Pricing
Most projects land between $4k and $25k
Fixed price after a 20-minute scoping call. No surprises, no padded hourly rates.
What moves you within the range
- How much product surface area we're building
- Whether we start greenfield or rescue an existing codebase
- Third-party integrations (Stripe, Supabase, AI providers)
- Whether you bring designs or we design as we go
Simple payment: 50% on kickoff, 50% on handoff.
