I'm a full-stack engineer based in   Hyderabad, India  with 7+ years across healthcare, real estate data, logistics, and enterprise software. I've shipped Redis caching systems that cut query times by 40%, HIPAA-compliant healthcare platforms, and CI/CD pipelines that halved deployment overhead.

Now I'm going deep on AI — building RAG pipelines, LangGraph multi-agent systems, and LLM inference infrastructure. Not as a pivot, but as the next evolution: production engineering experience applied to the hardest problems in AI deployment.

Education:   MCA — Netaji Subhash Engineering College · BCA — Global Institute of Science & Technology. Open to relocate. Targeting Senior SDE / AI Engineer roles.
