Hey! I'm Kuba — a 21-year-old software engineer with a web specialization. TypeScript is my primary language and I genuinely enjoy the type safety, the tooling, and the confidence it brings to a codebase.

On the frontend I work with React and Next.js, building fast and accessible interfaces. On the backend I reach for Go when performance matters, or Express.js / Nest.js for Node-based APIs. When the product needs to go mobile, React Native is my go-to.

I'm currently studying Computer Science while taking on freelance projects on the side. I care about clean architecture, good DX, and writing code that the next developer (or future me) will actually enjoy reading.
