About

I'm a Machine Learning Engineer based in Mumbai, India. I completed my M.S. in Computer Engineering at The University of Texas at Dallas (2024 – 2026) and build agentic AI systems, LLM applications and RAG pipelines that hold up in production.

At Mphasis I built an autonomous LLM-based QA agent with LLM-as-a-judge evaluation and a RAG system on ChromaDB and Azure OpenAI. Before that I shipped Python/Flask services as a software engineer at Shree Infotech, and Unity games in C# at two Mumbai game studios.

I care about systems that actually work in production, not just notebooks: reliable agents, measurable evaluation, and clean deployment with FastAPI and Docker.

Work Experience

Mphasis
Jun 2026 — Aug 2026 New York, US
Machine Learning Engineer
  • Developed an autonomous LLM-based QA agent (Python, Flask, Playwright) that browser-tests a production mortgage-income dashboard end-to-end and grades results against ground-truth keys via a multi-provider LLM layer (Claude, GPT-4o, Gemini, self-hosted Qwen).
  • Applied LLM-as-a-judge evaluation to replace manual QA, cutting per-case test time by 95% (minutes to seconds).
  • Built a synthetic data generator for 5 financial document types (W-2, paystub, VOE, Schedule C, P&L) with computed answer keys, scaling evaluation coverage to 200 cases per run with zero manual authoring.
