Who I Am

Hello.

I'm Piotr. I specialise in UI and frontend development.

I've been delivering web and UI solutions since 1996. Yes, that's over 30 years in the business. Over that long period, I've worked with a wide variety of companies and industries on countless digital projects. My goal is to provide high-quality UI and frontend solutions for every kind of digital project, from websites to web and mobile apps to e-commerce. I believe in simplicity, knowledge, experience, and focus. I have built my reputation on delivering value and great work.

Let's collaborate to bring your digital vision to life.

What I Do

  • Web and mobile applications

  • Modern web development

  • Responsive and adaptive user interfaces

  • UI and web consultancy

AI Workflows

Working with AI, not around it.

AI is fully embedded in my day-to-day development work. It isn't a novelty I experiment with on the side — it's part of how I plan, write, review, and ship code every day.

I work fluently with context engineering: giving a model the right information, in the right order, at the right time. I run multi-model agentic workflows, delegating to parallel agents, orchestrating them across a task, and picking the right model for each job. I build with MCP servers and custom tooling, and I treat prompts, agent instructions, and project context as first-class parts of a codebase.

What hasn't changed is the judgement. AI accelerates the work; experience still decides what's worth building, and what's worth keeping.
