01. About Me

I build secure, scalable backend systems that solve real problems. At Oracle, I've worked on Zero Trust platforms, cloud-native microservices, and PKI-based certificate infrastructure supporting large device fleets.

I care about reliability, simplicity, and thoughtful system design. Whether it's distributed APIs, Kubernetes deployments, or production observability, my goal is always the same: build systems that are clean, resilient, and easy to operate at scale.

Beyond work, I'm deeply curious about how systems — technical and otherwise — function. I enjoy breaking down complex problems to first principles and building solutions that genuinely help people, not just fill a portfolio.

I experiment and ship — from AI-powered tools to multiplayer games and Android apps — because the best way to understand technology is to build something real with it.

Technology isn't just my career — it's how I explore and understand the world.
