Summary

Senior iOS developer with nine years in software — from a first year in QA to shipping high-traffic consumer apps for the Austrian market (ÖAMTC, HEUTE, oe24) and running a freelance practice serving clients across Kosovo and Europe.

I build end to end: architecture, implementation, testing, App Store release, and everything after. Currently going deep on AI-assisted products and developer experience.
