The curious software engineer

Hey there, I'm Sergei. I'm a senior software engineer who likes to build things since childhood. I'm always curious about new things in tech, so I'm always working on something new. Right now I'm helping to build AirConsole (a gaming console for cars) at N-Dream. Before that I worked in a couple of agencies making web applications, websites and other apps.

My natural curiosity led me to many different domains, and I tried to get the best out of them. My IT career started in QA, so I care a lot about the quality of everything I do.

I'm based in Zürich, and you can also find me on GitHub and LinkedIn. You can check out my story and projects I've worked on below.

My story

Well, I like tech in all kinds and I've been always curious how everything works. So I've started from breaking software as a QA and then learned how to build them better as a software engineer.

Senior software engineer, then tech lead, at what. AG
Fully switched to software engineering, built a lot of websites, CMS extensions, apps and products. Oversaw the whole company tech strategy in the meantime. I've learned many engineering skills during that period of time, built around 60 projects. Also I've discovered and adopted AI into my daily engineering routine. So AI agents are helping me to build stuff day and night since 2025

Being a tech lead was fun, but I always wanted to build more myself. I also like driving and video games, so this match was inevitable
