On the web since 2004 · 22 yearsIndependent studio, Poland Taking on a small number of new projects

Clean on the surface.Engineered underneath.

CTO, engineer and system architect. I design and build web platforms end to end, from the interface people touch to the databases, cloud and integrations they never see.

Experience first

Built on experience. Sped up by AI.

I design the architecture, make the decisions and build the systems myself. AI is one of my tools: it takes the repetitive parts off my plate so I can move faster. On its own, a model will happily build the wrong thing, quickly and confidently. What it can't bring is twenty years of shipping: knowing which stack fits, which pattern will still hold at ten times the traffic, and what a system should cost to run.

There's nothing wrong with starting from a prompt. The difference shows later: when the bill arrives, when traffic doubles, when something breaks at the worst moment. That's the part I'm here for.

  1. 01

    The right stack

    Chosen for your product, your team and your budget, not for what's trending this month.

  2. 02

    The right architecture

    Patterns that keep the system simple today and easy to change tomorrow.

  3. 03

    The right budget

    Infrastructure sized for today, with a clear path to grow. You pay for what you use, not for what you might need.

  4. 04

    A plan for scale

    Each part can grow on its own, so growth is a decision, not a rewrite.

  5. 05

    AI as a helper

    It speeds up the routine work. Every line that reaches you is written or reviewed, tested and owned by me.

  6. 06

    A person to call

    When you need help, you reach the person who designed your system and knows why every part is there.

Origin

It started with Flash, in 2004.
