About

Building ML systems that ship — from power grid forecasting at IISc Bengaluru to production RAG pipelines serving enterprise clients in the Netherlands. My stack: XGBoost · LightGBM · Transformers · LangChain · LangGraph · CrewAI · FastAPI. I care about the full loop: feature engineering → model dev → low-latency inference → monitoring. Lately I've been designing multi-agent and HITL workflows for LLM-powered search — and co-authoring a paper currently under review at International Journal of Medical Informatics. A few things I'm proud of: → Top 12 National Finalist, Novartis Hackathon 2025 (out of 1000+ teams) → TEEP Scholar — Taiwan government research fellowship at NKUST → Research at IISc Bengaluru (Kotak-funded, highly competitive) Open to full-time ML Engineer or Applied Scientist roles.
