Senior Software Engineer & Ads ML Researcher @ Meta
Ex-Rocket Scientist @ ISRO
Santa Clara, CA
I design and ship ML systems that reach billions of people spanning ads targeting, ads ranking, retrieval, LLM fine-tuning, and recommender systems at Meta. Before that, I optimized large-scale ML pipelines at Apple and led satellite launch and post-launch operations at ISRO. I thrive at the intersection of ML and large-scale systems engineering, and love working on problems that are genuinely fun and satisfying to solve.

Open-sourced a local-first macOS voice-typing app with on-device Whisper transcription, an LLM command mode, and tone rewriting.
Fine-tuned Qwen 2.5 3B with DPO on a $0.44/hr GPU, hitting seven real errors along the way, then used Claude as a judge to confirm the tuned model wins two to one.
A no-nonsense tour of the LLM jargon everyone throws around, from SFT, DPO, and LoRA to vLLM, agents, and the harness, all mapped onto one mental picture: a car.
