What I'm looking for

I’m looking for a team where I can build and scale distributed backend systems end-to-end, improve reliability through strong observability, and optimize performance and security in production high-traffic environments.

I’m a software engineer with around 9+ years of experience building scalable web applications and distributed systems across backend services and user-facing platforms. I focus on delivering production-grade systems, collaborating closely with product and design teams, and improving reliability and performance in high-traffic environments.

Most recently at Meta, I developed distributed backend services with Python, Node.js, and GraphQL, and built serverless APIs on AWS Lambda, API Gateway, and DynamoDB. I also strengthened observability with Datadog, Prometheus, and Grafana, optimized performance with PostgreSQL indexing and Redis caching (reducing query latency by 120ms+), and enhanced security with OAuth2, JWT, and SSO—helping deliver robust, high-availability systems.
