Building elegant, maintainable solutions with a strong focus on testing since 2010. Passionate about clean code, Japanese culture, and storytelling through photography.

About Me

Who I Am

I'm a self-taught full-stack software engineer with over 15 years of experience working for global companies. Frontend-oriented but comfortable across the entire stack, I specialize in building elegant, performant web applications that solve real problems.

Outside of coding, I'm passionate about Japanese culture and language learning. I collect manga, build Gunpla, love to travel (especially in Japan, though Switzerland is quickly becoming a favourite), and document my journeys through photography.

I keep things simple and focused, aiming for clean solutions without unnecessary complexity.
