Full-stack developer with 4+ years building scalable, production-grade web apps using React.js, Next.js, Node.js, and AWS. I design high-performance REST APIs and microservices, cutting backend latency by up to 40% with Redis caching. Recent work: an event-driven chat platform for 1,500+ concurrent users at sub-80ms latency, and a real-time app built for 15k+ users.
