What I'm looking for

I'm open to part-time contract and overflow work.

At Open Kinetix DOO, I delivered production web and mobile products across fitness, food ordering, recruitment, aviation, fintech, and AI. For a white-label fitness platform, I was the primary engineer on a React Native and Expo product built from scratch for multiple consumer brands, including its architecture, major screens, integrations, and app-store releases.

I also created the monorepo foundation for a multi-channel food ordering platform and delivered mobile migration and CI/CD work for a global staffing platform. I created Tenkit, an Expo and React Native toolkit for generating white-label and runtime-tenant apps from one codebase. I'm open to part-time contract and overflow work.
