About

I worked at Carrier Fire & Security Polska as a Sr Associate, Digital Software Developer, focusing on backend development and data warehousing. My daily work included programming in Go and TypeScript, as well as building and maintaining cloud infrastructure on AWS (using AWS CDK). I hold a degree in Data Engineering from Gdańsk University of Technology. Beyond my professional work, I am passionate about cybersecurity and developing web, desktop and iOS applications. I led the CTF team in the PING student research group at Gdańsk University of Technology, where I also served as chairman during 2022/2023. CTF team profile: https://ctftime.org/team/147266 Student research group: https://knping.pl/ Since 2022 I've been participating actively in CTFs with justCatTheFish team, focusing on web and misc challenges. Occasionally, I also create software solutions and desktop tools for A&A Biotechnology.
