Full Stack
Developer.

4 years building products. Former game developer. I'm always learning, with the goal of building things that are useful to more people. Even in small ways, seeing someone use what I've made means a lot to me.

02 — The Origin

Game
Dev.

Before web apps, there were worlds. I spent ~2 years building games in Unity — hyper casual games, playable ads — and shipping them to publisher companies - Crazy Labs, Supersonic Studios LTD. It taught me that users feel everything, even the things they can't name.

03 — The Craft

Full
Stack.

I build things that work — solid APIs, interfaces that just feel right. My game dev background meets real production engineering. Here's some of my work:

Experience

Built an internal kitchen staffing forecast system pulling attendance data from ~20 ZKteco biometric devices across sites to predict meal counts for morning, lunch, and dinner shifts. Replaced vague headcount estimates with data-driven forecasts accurate to within 15-20 people, cutting kitchen overcooking costs by 50 million MNT over 6 months.

04 — Why I'm Applying

From building
to understanding.

Four years of shipping production software — banking platforms, forecasting systems, AR museum tours — taught me how to build things that work. What I want now is the theoretical depth that turns "it works" into "I know why it works, and how to make it work better." A Computer Science degree in Poland is where I want to build that foundation: rigorous CS fundamentals, a European academic environment, and the chance to finally formalize the systems-thinking I've only picked up through trial and error on the job.

NowFull-stack & game developer, 4 years — Next.js, TypeScript, MySQL, Unity, C#.
Why CSI can build features; I want to understand algorithms, systems, and theory deeply enough to design them, not just assemble them.
Why PolandStrong, affordable CS programs with a rigorous European academic tradition and a path to work across the EU after graduating.
GoalGraduate equipped to design systems from first principles, not just implement them — and bring that back into harder engineering problems.
