Independent developer · Warsaw

Production sites,AI agents and mobile apps.In 1 to 3 weeks.

I'm Alex. One developer who builds, ships and supports the whole product — from first call to live launch.

Warsaw · Available worldwide · RU / EN / PL / UA

Why work with me

Three reasons clients keep coming back.

Weeks, not quarters.

Agencies take three months and four meetings to do what I deliver in three weeks. One person, one decision, one ship date.

One person. The whole stack.

You message me directly. No account managers, no Slack channels, no handoffs to a junior. The person you brief is the person who codes it.

Built to rank from day one.

Technical SEO, schema, performance and content structure aren't a separate phase — they're baked into the build. Pages indexed within hours.

Frequently asked

Answers, before you ask.

  • A marketing site typically goes from kickoff to live in 2 to 3 weeks. Larger sites with custom integrations or multilingual content can take 4 to 6 weeks. Either way, you get a fixed launch date in writing before the project starts.

  • Yes. I'm based in Warsaw and work with Polish clients regularly. I speak conversational Polish, fluent English and native Russian / Ukrainian. Contracts can be signed under Polish law and invoicing is handled with VAT EU.

  • Yes. Several of my projects ship in PL / EN / UA / RU simultaneously. I handle proper i18n routing, hreflang, locale-specific SEO and content translation review with native speakers.

  • You get 30 days of bug-fix support included. After that, edits are billed at €50 per hour with a one-hour minimum. There is no forced monthly retainer — you only pay when you actually need work done.

  • AI agents start at €1,200 for a focused use case (a FAQ assistant, a lead qualifier, a single-tool automation). Multi-tool agents with CRM and database integrations typically land between €2,000 and €5,000. Final price after a 30-minute scoping call.

  • Yes — I build cross-platform from a single codebase using React Native and Expo, then submit to both the App Store and Google Play. If a project genuinely needs platform-native, I'll tell you upfront and quote accordingly.

  • You message me directly. No account managers, no junior developers handling your project while a senior signs off. The person you brief is the person writing the code. Decisions take minutes, not weeks.

  • Yes — that's the default, not an upsell. Every site I build ships with technical SEO, schema markup, hreflang for multilingual pages, optimized Core Web Vitals and IndexNow pings on deploy. Most pages index within hours and start ranking within weeks.

  • Always. Every project starts with a written agreement covering scope, payment schedule, IP transfer, deadlines and what happens if either side wants out. Contracts can be in English or Polish.

  • Edits are billed at €50 per hour, with a one-hour minimum. No forced monthly retainer. You can come back six months later for a small change and I'll handle it — same terms, same rate.
