What I'm looking for

I'm looking to bring end-to-end feature ownership, reactive state-management, component architecture, and pixel-perfect UI work to a frontend-focused team.

I've built mobile products at Atlaslive, including a white-label sports betting and iGaming platform powering 25+ branded iOS and Android apps from a single Flutter codebase.

I owned real-time sportsbook experiences including live and pre-match betting, betslips, cash-out, free bets, VIP bets, and WebSocket reconnection. I also developed account, biometric login, KYC, payment, transaction-history, and responsible-gaming features, integrating Firebase, Veriff, Legitimuz, CAF, and Zendesk.

Previously, I contributed to a BTC and USDC crypto wallet, building account, security, personalization, KYC, registration, and JWT-authenticated API features in Flutter.

My earlier Angular work included DoctorOnline CRM for clinic doctors and administrators, with patient records, appointments, role-based access, Reactive Forms, and NgRx state management. I'm looking to bring my end-to-end ownership—from architecture and reactive state management to pixel-perfect UI—back to a frontend-focused team.
