About

I am currently an Engineering leader at Meta Platforms operating at the intersection of AI, large-scale distributed systems, and monetization. I build and scale AI-native platforms that power global products leveraging generative AI, autonomous systems, and advanced ML to drive step-function improvements in performance, reliability, and engineering velocity. My focus is on re-architecting systems for the AI era: evolving traditional cloud and data platforms into intelligent, self-optimizing infrastructure. I lead high-performing teams delivering resilient, privacy-aware, and highly efficient systems that adapt in real time to dynamic workloads and rapid product innovation, supporting millions of businesses at global scale. I have a proven track record in building 0→1 and 1→N platforms, driving org-wide transformation, and embedding AI into the core of engineering, product, and operations. I’m particularly interested in shaping the next generation of autonomous, AI-first systems where intelligence is built into the fabric of the platform, not layered on top.
