About
Hi, I'm Josip.
Senior cloud software engineer. 8 years in production systems. Working on AI on the side.
My story
I'm a cloud software engineer at a large tech company. Eight years building production systems, Master's in Computer Science. Mostly TypeScript these days, some Go for the services that need it, and Next.js when I'm tinkering at night.
Outside work I read philosophy, cycle and ride motorcycles when the weather permits, and play semi-professional American football on the offensive line. Back on the field since 2022 after a freak injury took me out of the sport.
Lately the interesting stuff is agentic systems and pictwinai, an AI image-generation product I run on the side. That's how I ended up taking on a handful of AI projects each year for other teams. If yours could use help putting AI into real software, the contact link works.
