Expertise
What I do
Frontend Engineering
I architect and deliver production-grade frontends at scale. From leading micro-frontend migrations at a banking platform to building real-time sportsbook interfaces with WebSockets, I thrive on complex UI challenges. I'm deeply opinionated about design systems, performance profiling, and maintainable component architecture — and I bring TypeScript and testing discipline to every codebase I touch.
Backend & Cloud
I've built and owned backends across diverse stacks — from queued payment systems with Redis and BullQueue, to AWS event-driven workflows using CDK and Lambda, to high-performance Go APIs with Redis caching that cut latency by 40%. I integrate AI capabilities (Claude AI + RAG + Pinecone), design JWT authentication middleware, and build asynchronous notification systems that hold up under load.
Mobile Development
I've shipped mobile apps from zero to launch across multiple markets. Built React Native apps for sportsbook promotions, tenant communication platforms, and corporate event management. Led the Matchroom mobile platform launch across Malaysia and Thailand. I understand the full mobile delivery pipeline — from architecture to App Store — and bring the same quality bar I apply to web.
