What I'm looking for

I seek backend/cloud roles where I can build reliable, scalable services, improve performance, and drive measurable product impact within collaborative, engineering-driven teams.

I am a senior software engineer with strong backend, cloud and API experience, built on an IIT Indore B.Tech foundation. I have designed and delivered production services—dashboards, billing integrations, trial flows, liveness-detection, subtitle pipelines and data-sync systems—using Python, Flask, SQLAlchemy and AWS.

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.
