IndiaWhat I'm looking for
I am a senior software engineer with strong backend, cloud and API experience, built on an IIT Indore B.Tech foundation.

I focus on measurable impact: reducing API latency from seconds to ~100ms, enabling subtitle generation at scale for 20,000+ videos daily, implementing robust CI/CD and containerized services, and improving security and reliability through ACLs, retries and monitoring integrations.
