About me:
Hi there! I'm a Mobile Developer with two years of commercial experience. I
love building modern, high-quality, and user-friendly mobile apps. A huge highlight of
my career was my two-year journey at the "Porada" startup. I was a core part of the
engineering team and actively contributed to developing two products simultaneously
– "Porada" and "Porada Business". My technical solutions helped bring these apps
all the way from the initial concept to a successful release on the App Store and
Google Play.
I always approach development with the end product and the user in mind.
Currently, alongside my main job, I’m developing my diploma project – "Mayak", an
offline-first civil protection mobile navigator. On top of that, I independently develop
and monetize mobile games. I enjoy writing clean, scalable code and am constantly
leveling up my technical skills. I'm looking for exciting, complex challenges in a
product-focused company where I can apply my expertise and make a real impact.
