01 — About
Who I Am
Senior AI/ML engineer and technical lead at Meta AI, driving post-training and inference optimization for multi-modal LLM systems at massive scale. Former founder of Momento AI, and engineering alumnus of AWS, Coinbase, TikTok, and Magic Leap.
My work lives at the boundary of systems engineering and machine learning — designing agentic AI pipelines, hardening them against adversarial prompt injection and tool misuse, and squeezing maximum throughput out of GPU inference infrastructure for production workloads serving billions of users.
Pursuing an M.S. in CS (ML/AI) at Georgia Tech while shipping production systems — because the best engineers never stop learning.
