What I'm looking for

I'm open to global remote roles and relocation within the EU.

At Price Match Game, Dubie, I lead mobile development for a real-time, cross-platform competitive gaming application. I engineered WebSocket mechanics for user matching and low-latency state synchronization, and refactored caching and state management to address UI memory leaks and improve frame-rate responsiveness.

At Tribes, I architected mobile solutions including WriteUpp’s secure clinic payment system, which integrated Stripe Terminal, NFC, Bluetooth, Apple Pay, and Google Pay and achieved a 99.9% transaction success rate. Earlier, I built and deployed white-label apps at Vagani and engineered real-time communication modules, chat, and push notifications.
