Flutter mobile engineer delivering real-time, scalable fintech and e‑commerce features.
United Arab EmiratesWhat I'm looking for
I am a mobile engineer specializing in Flutter, focused on building real-time, production-grade applications for fintech and e-commerce. I have shipped end-to-end features across iOS, Android, and web while collaborating closely with product, design, and backend teams.
My work includes implementing WebSocket-driven systems, payment integrations (Stripe), and scalable architecture patterns like Clean Architecture with unit tests to reduce regressions. I have driven measurable improvements such as crash rate reductions, fewer support tickets, and improved trader satisfaction during high-volume periods.
I prioritize reliability, performance, and maintainability, bringing experience across CI/CD, Firebase, TradingView integrations, and monitoring tooling to ensure features reach users quickly and robustly.
