ABOUT ME

Who I am

I'm a full-stack engineer with a DevOps-first mindset. Java at the core, infrastructure by conviction.

I don't just write code - I think about how it gets built, tested, deployed, and monitored. CI/CD pipelines, containerization, cloud workflows, observability stacks - I'm obsessed with the entire lifecycle, not just the feature branch.

Currently a Level 5 undergraduate at IIT Sri Lanka, moving into my third year. I've built real-time tracking systems, chaos engineering tools, AI-powered API gateways, and infrastructure simulators - not for coursework, but because the best way to learn is to build things that actually work.

I'm fluent across the stack - Java, Python, TypeScript, Go - and equally comfortable writing REST APIs, configuring Kubernetes clusters, setting up Prometheus dashboards, or debugging a Kafka consumer group. I write tests, I read logs, and I believe every system should be observable by default.

Right now I'm working through a structured 64-topic DevOps learning journey - Docker to distributed systems - and actively exploring internship opportunities where I can bring this energy to a real team.
