The stack is Python, FastAPI, Azure OpenAI \(GPT\-4o\), Azure AI Search, and LangGraph\. Most of my work is the unglamorous part of making LLM systems dependable: production RAG with layout\-aware document parsing and hybrid retrieval with semantic reranking; schema\-validated structured outputs; agents that recover from failed tool calls; and grounded\-refusal guardrails, so the system declines rather than invents\. An evaluation harness scores groundedness on a fixed test set and gates every prompt and retriever change before it ships — evaluation is part of the system, not an afterthought\. Outside work I build open\-source developer tooling around LLMs and the Model Context Protocol \(MCP\), and I contribute upstream to the LLM ecosystem\. Before this, I worked in applied data science: Bayesian marketing\-mix modelling in Google Meridian at Analytic Edge \(C5i\), NLP and causal inference on pharma problems at Axtria, and an internship at AbbVie building predictive models on longitudinal patient data\. That grounding in statistics and classical machine learning shapes how I build with LLMs: measure first, then ship\. MS in Business Analytics from UC Irvine, where I was a Dean's Scholar\. ## Location Hyderabad ## AI stack anthropic apis antigravity claude code claude elevenlabs gemini ## Work experience Senior AI Engineer at Motherson Technology Services, Nov 2025 \- Present · 10 mos, Hyderabad, Telangana, India, • Build the complete backend for three enterprise generative AI products on Azure\.
