ABOUT ROHIT SINGH
A software engineer who builds infrastructure that powers intelligent products at scale. At Meta, I\'m developing production AI systems for Facebook and Instagram\'s customer support—fine-tuning foundation models like Llama 4 and Gemini Pro, architecting real-time context management systems, and building end-to-end monitoring infrastructure that enables confident deployment to 100% of US and Canada users. Before Meta, I spent three years at Google scaling infrastructure for services, where I built deployment frameworks that enabled critical products like Gmail, Search, and Cloud to ship configuration changes in minutes instead of hours. Whether optimizing distributed systems or shipping AI features that serve hundreds of millions, I thrive at the intersection of infrastructure reliability and product velocity.My journey reflects a belief that great infrastructure empowers great products. Now at Meta, I\'m working at the frontier of AI infrastructure—designing systems that blend foundation models, distributed computing, and product thinking to make AI reliable at massive scale. I hold a Master\'s in Computer Science from UT Austin and a Bachelor\'s from IIT Delhi. I\'m passionate about building infrastructure that doesn\'t just work—it enables teams to innovate faster, products to scale effortlessly, and technology to reach its full potential.
