Experience
Starting in November 2025, I joined Transition Technologies PSC as a senior front-end Angular developer
Previously, from early 2023 until November 2025, I worked at Pentacomp as a front-end Angular developer in the healthcare sector. I contributed to building solutions used daily by millions users, including Internetowe Konto Pacjenta (Patient's Online Account).
During my time at Pentacomp, I also spent a bit over 10 months supporting Aplikacje Krytyczne team in developing a system for managing tax-related processes.
Before that I worked at MobileMS, where I helped build numerous websites for Polish museums, including National Museum in Warsaw, The Ethnographic Museum in Krakow, and Museum of Eastern Borderlands.
Having worked on multiple publicly funded projects, I am well versed in WCAG and experienced in creating accessible websites and writing semantic, standards-compliant code.

Thanks to the Erasmus+ Programme I was lucky enough to have studied at universities in Poland, Malta and Turkey:
- West Pomeranian University of Technology, Poland (my main university)
- University of Malta, Malta (Erasmus)
- Mugla Sitki Kocman University, Turkey (Erasmus)
About me
When it comes to my personal interests, I love travelling, motorsport and photography. Other than that, I enjoy studying linguistics. Of course this doesn't make me a polyglot, but I do speak a couple of languages:
- Polish (native)
- English (C1)
- Spanish (A2/B1)
- German (A1/A2)
