Why work with me

Why clients pick me over an agency.

  • 01

    Weeks, not quarters.

    Agencies take three months and four meetings to do what gets shipped here in three weeks. Minimal back-and-forth: one decision, one ship date.

  • 02

    No middlemen. The whole stack.

    You talk straight to the people designing and writing the code. No account managers, no endless Slack channels, no handoffs to a junior.

  • 03

    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.

Selected work

Five launches in production.

Real clients, real results, real numbers.

Launched our store in 11 days — multilingual, fast, and already on page one for three of our main keywords.

The Telegram bot handles the first conversation with every lead now. My sales rep only steps in when the deal is hot.

Leads land in our CRM with every field already filled. No more copy-pasting from chats — the pipeline moves itself.

Shipped to the App Store and Google Play in three weeks. The handover docs let my team take it from there without me.

Set up our Google and Meta ads from zero. Cost per lead dropped by about a third in the first month.

He rebuilt the site and six weeks later ChatGPT was recommending us by name. Didn't know that was even possible.

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 €500 for a focused use case (a FAQ assistant, a lead qualifier, a single-tool automation). A sales agent with CRM is from €1,500; a multi-tool agent with integrations runs €3,000–8,000. 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.

  • We work across all of Poland and remotely — Warsaw, Kraków, Wrocław, Gdańsk, Poznań or a smaller town, it makes no difference. Calls, demos and handover happen online; the contract and payment are remote. An in-person meeting in Warsaw is available on request.
