About

Nice to meet you!

My name is Jakub, friends call me Kuba. I'm a Senior Software Engineer specializing in frontend architecture and product quality, with experience designing and developing enterprise-scale web applications using Angular, TypeScript and RxJS. I combine strong engineering expertise with a broader product perspective — analysing requirements, challenging assumptions, and designing maintainable solutions.

I work well in complex, distributed environments where technical decisions have direct business impact. I like strengthening engineering practices through code reviews and knowledge sharing, and I care about scalable, sustainable software delivered by teams that trust each other.
