Hi, I’m Josip.

I turn AI ideas into useful software. Eight years of production engineering, alongside products I build and run myself.

The short version: I help turn AI ideas into outcomes a business can measure, then build the software to get there. I also build and run my own products, including pictwinai.com and grouped.news, which keeps my work grounded in what happens after the first demo.

The credentials, since they matter when you’re handing someone your roadmap: eight years engineering production systems, including cloud work at a large tech company, and a Master’s in Computer Science. Mostly TypeScript, Go for the services that need it, Python where the AI work lives. Agentic systems are what I’m deepest in right now.

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.

If you have an idea, or a problem you think AI could help with, bring it along. We’ll look at the opportunity together and agree on a sensible first step before any paid work begins.

Where it earns its keep

Outside work.

  • ReadingPhilosophy mostly. Stoics, ancient and modern, and the odd computer-science classic.
  • Cycling & motorcyclingLong routes when the weather lets me, both pedalling and otherwise.
  • American footballSemi-pro, offensive line. Back at it since 2022.
Bring the idea. Leave with a clear next step.
