About Me

I’m a backend-first engineer working across the full stack when needed. I design systems that scale from MVP to production with reliability, security, and clean architecture.

I actively work with Node.js, Fastify, Kafka, Kubernetes, and cloud-native tooling. I’m also a student of ethical hacking and deeply interested in system security.
