Profile picture

Hi, I am Filip and I love to build software, which can take many forms. Ranging from simple utilities, web applications to native iOS applications, but I prefer to write backend software over the frontend one. I enjoy writing software that automates routine tasks, saving time, money and energy of humans.

Since 2024, I am also certified HAM radio operator (HAREC class A) and my call sign is OK1GOD.

I can speak Czech (native) and English language.
