Most projects fail not because the code was bad, but because they spent months building the wrong thing. An MVP flips that – you ship something real, put it in front of real users, and learn before committing to a full build.
I work from Finland (UTC+2) with founders across the EU and Nordics – building lean, deployable MVPs. I’ve built them for SaaS tools, internal dashboards, fintech platforms, and e-commerce products. The goal is always the same: a working product you can show to investors, users, or stakeholders – built lean, but built properly.
‘Lean’ doesn’t mean throwaway. The codebase you get is clean and production-ready – something you can actually build on, not something you’ll need to rewrite in six months.
We identify the one thing the MVP must do well. Everything else goes on the backlog.
A written spec: what’s in, what’s out, what the first milestone looks like. No surprises.
Working software from day one. I share progress regularly – not just at the end.
Deployed to production, with documentation. You can run it, extend it, or hand it to another developer.

Open-source spec and engine that turns straight quotes, hyphens and three dots into curly quotes, dashes, ellipses and no-break spaces for 10 locales.
Zero-dependency Halloween corner decorations and ambient effects – one script tag or npm install, class-driven, seasonal by default, under 10 KB gzipped.
40+ point production SaaS checklist: auth, Stripe billing, PostgreSQL, rate limiting, email, monitoring, and security – with honest 8-week build estimates.
API key management for a public SaaS: hashing keys at rest, prefix + last-4 display, fail-closed validation, and revocation.
Subscription billing edge cases Stripe glosses over: proration, dunning, the state machine, cancellation timing, refunds, VAT, and webhook ordering.
I came in with a 40-page spec and Iurii immediately told me half of it didn’t need to exist for the first version. That was uncomfortable to hear but he was right.

I had a validated idea and a deadline tied to an accelerator demo day, but no product.
