About
I'm Ivan Blajić, a software engineer from Split, Croatia, with a master's degree in computer science and more than fifteen years of native iOS development behind me. I've built and shipped apps used by millions — TV streaming, travel and ticketing, sports and entertainment — for companies across Europe.
BlayaSoft is where I build my own: focused, reliable tools with an instrument-like feel, designed to work offline and in the field.
Custom work
Need one of my apps to do something it doesn't yet — a custom feature, map layer or integration tailored to your team's workflow? I build custom solutions on top of my existing apps, and I'm always open to interesting client projects of any kind, from first concept to the App Store.
