I’m an AI/ML Engineer at Vansun Venture (91Trucks), focused on shipping production GenAI systems that are measurable, fast, and safe. I designed and deployed a Saarthi RAG chatbot using LangChain, Sentence Transformers, and pgvector on PostgreSQL, and improved reliability with confidence-threshold fallback (cutting hallucination rate to 30% on a 50-query golden set).
I also build intelligence pipelines end-to-end: a geospatial dealer recommendation service with Ball Tree KNN and PostGIS indexing (reducing latency to <80ms P95), a call intelligence platform processing 400+ daily recordings with Whisper and diarization to reduce domain WER from 20% to 8%, and an automated vehicle document IDP cascade achieving >91% extraction accuracy. Alongside this, I’ve architected ETL for 80k+ auction listings/week and integrated natural-language SQL querying with a LangChain SQL Agent—plus agentic LangGraph workflows that reduce documentation time by 80%+ while enforcing structured outputs and LLM safety checks.
