I design and build software to serve customers at scale. I also write and speak about systems, engineering, and organizations.

I’m currently a Senior Software Engineer at Allegro Pay, where I work on one of the fastest-growing fintech platforms in Poland. I have hands-on experience in creating web applications and server-side services with a broad knowledge of the Microsoft technology stack including Azure Cloud. My focus is on building and maintaining products like Allegro Cash (cashback), Allegro Care (insurance), and Allegro Pay (loans). Recently, I’ve been exploring areas like system reliability, documentation standards, and people management. I also support the recruitment team as a bar raiser and technical recruiter, specializing in system design interviews and building a winning team.

Outside of work, I spend my time cycling with my brothers and reading books.
