## About

I care about the gap between a working demo and a system that holds up in production — retrieval precision, inference latency, multilingual tokenization, and the data decisions that make models actually useful for Indian users\. What I've shipped: → Production RAG chatbot for National Institute on GCP — 15,000\+ queries, sub\-2s latency, hybrid FAISS \+ BM25 retrieval with cross\-encoder reranking\. Optimized inference 60% \(5s → 2s\) via FP16 quantization and GPU batch parallelism\. → Multi\-agent IT/HR platform \(NeuraDesk\) — 4\-node LangGraph system with DSPy\-compiled classifier \(66\.7% → 93\.3% accuracy\), A2A protocol endpoint, and production safety gates\. 111 tests, deployed on GCP Cloud Run\. → Offline multilingual voice agent \(Yojana Sahayak\) — Whisper ASR → QLoRA fine\-tuned Qwen2\.5 → FAISS RAG → TTS\. Zero internet dependency\. MCP tool\-calling server for 591\+ government schemes\. Model and dataset open\-sourced on HuggingFace\. → QLoRA fine\-tuned Qwen2\.5\-1\.5B on 39,957 bilingual Hindi\-English instruction pairs — perplexity 1\.15, trained in 54 min on Kaggle T4\. Competitions: 🏅 Top 12 / 118 teams — NCIIPC Startup India RAG Document Retrieval Challenge 🏅 Top 3 / 100\+ teams — Apollo Hospitals × IIT Delhi Medical AI Solvathon Stack: LangGraph · LangChain · DSPy · MCP · A2A · FAISS · BM25 · Whisper · QLoRA · vLLM · FastAPI · GCP · Docker Currently building GenAI and agentic AI tooling in a Managed Services capacity at PwC India — Delhi NCR\.
