I’m a Senior Full Stack Engineer with 6+ years of experience designing and shipping high-performance, scalable web and mobile applications. I build reactive UIs for dense, real-time data feeds and pair them with robust backend services—REST APIs, microservices, and event-driven architectures using Redis and RabbitMQ.

At OPPTY (Singapore, Remote), I led frontend architecture and full delivery of OppTy v1.0, owning React components end-to-end from wireframes through app store deployment. I built real-time, data-dense interfaces with Socket.io—optimizing rendering, virtualization, and state management for time-series updates with zero perceptible lag. I also improved platform security (JWT, OAuth 2.0, RBAC), handled incidents across React and Node.js, and managed CI/CD and AWS deployments (EC2, S3, ELB) for both web and React Native (Expo).

Previously at EXCELGAMES INTERACTIVE, I delivered real-time diagnostic dashboards using React.js, Next.js, and React Native (Expo), including live BLE hardware data streams in dense, interactive UIs. Earlier, at GROUNDZERO HOLDINGS, I built a production social platform and job board (React, Redux, React Native) and optimized Node.js/MongoDB backend performance; before that, I contributed to full-stack projects during my Software Engineer Trainee role at SLIIT.
