What I'm looking for

I seek backend or platform roles where I can build scalable, secure distributed systems, work with CI/CD and cloud infrastructure, and grow within a collaborative, engineering-driven team.

I am a backend-focused software engineer (B.Tech 2025) who builds production-grade distributed systems using Go, Python, and JavaScript/TypeScript. I design and implement scalable infrastructure, REST APIs, and fault-tolerant services with a strong emphasis on performance and reliability.

My notable projects include a webhook delivery platform sustaining 448 req/s with 0% error rate, a secure authentication service with JWT and rotating refresh tokens, and a real-time multiplayer quiz with sub-second synchronization. I contribute to open source (redis/go-redis) and maintain packages for the Arch Linux AUR.

I follow DevOps practices—Docker, Kubernetes, CI/CD, Terraform, and AWS—to deliver secure, observable, and recoverable systems. I prioritize secure coding, automated testing, and pragmatic optimization to reduce latency and improve throughput.
