01 / About

Building the
Invisible Layer.

I'm a backend-first engineer who architects the systems that power modern applications — the APIs, event queues, caches, and databases that users never see but always depend on.

With 4+ years across fintech, real-time apps, and consumer platforms, I specialize in Node.js microservices, Rust performance layers, and cloud infrastructure that scales without flinching.

Hands-on with AI-assisted development (GitHub Copilot), Kafka-driven architectures, and cross-functional Agile teams. I write code built to last.
