# About

## background

I am a Product Engineer based in Bielsko-Biała, Poland. My engineering journey began deeply rooted in the mobile world. For years, I specialized in React Native—crafting smooth 60/120fps interactions, building custom native modules across iOS and Android, and optimizing rendering pipelines with Reanimated and gesture-handling primitives.

Shipping complex client applications naturally expanded my scope across the entire product lifecycle. I moved into building performant web applications, design systems, and frontend architectures, and gradually took on production backend responsibilities. Today, I build and maintain end-to-end systems: from responsive mobile and web interfaces to serverless edge functions, SQL databases, and resilient APIs running on production infrastructure.

## philosophy

• Pragmatic simplicity:Clear, readable code with explicit boundaries beats opaque abstractions every time. Systems should be understandable on first reading.
• Speed through verification:Confidence comes from fast, rigorous automated feedback loops—strict typing, linting, accessibility contrast checks, and focused unit tests.
• User-centered outcomes:Code has value only in service of what real users experience. Architectural choices should serve reliability, performance, and user joy.
• End-to-end ownership:Understanding the whole stack—from the pixel on glass down to the edge worker and database query—enables making better tradeoffs early.
