education: B.Sc. Computer Science — Sunway University, MalaysiaI design and build high-load banking platforms in fintech — microservice architectures (~90 services scale), fault-tolerant integrations, and event-driven workflows on Camunda + Kafka. I lead engineering teams, run code reviews, and care a lot about API-first design, observability, and code quality.
When I'm offline from Java, I write — on Medium, Substack, and Ghost — about the JVM, Spring internals, distributed systems, and the craft of software engineering.
