About Me

Final year B.E. student at Sinhgad Institute of Technology & Science, Pune. I specialize in bridging complex AI logic with robust backend infrastructure — specifically RAG systems, LLM orchestration, and scalable API design using Django and vector databases.


Currently building Meridian, a cross-platform productivity app with AI-powered voice transcription, and DocuMind, a production-grade RAG platform with hybrid search and ML evaluation pipelines.
