01 · ABOUT ME
Hi! I'm Szymon - a web & mobile developer from Wrocław, Poland. I'm operating throughout the whole stack in the widest meaning possible, ranging from devops, cloud, databases, backend, RAGs, AI agents, data pipelines, frontend, mobile and even desktop apps and anything in between (e.g. ms office plugins).
My tech stack of choice is anything typescript-based or dart-based, but I'm pretty comfortable with most modern tech. Big Flutter advocate and daily typescript user at Alergeek Ventures.
Off the clock you'll find me contributing to open-source projects or coding and mentoring at Solvro, a science club I've helped to become the biggest IT student science club in Poland (disclaimer: it's a self-claimed title, but we're pretty sure).

Beyond the day job
I build a lot on my own or with friends!
Checkout my personal projects, hackathons, open-source packages, apps and websites. I never let my passion for the software craft die and still consider it my daily hobby.
