With over 20+ years of global experience, I am a senior software engineering leader specializing in building high-scale, enterprise-grade platforms. Currently a Principal Engineering Manager at Microsoft, I lead the M365 Copilot Agent Query matching and grounding stack, focusing on AI-driven search, Retrieval-Augmented Generation (RAG), and vector search infrastructure. My background includes significant leadership roles at Apple, where I managed Apple PKI services and AWS cloud migrations, and at Capital One, where I architected identity proofing and authentication systems. I have deep technical expertise in distributed systems, FinTech, and cybersecurity, combined with a strong foundation in engineering excellence and strategic team leadership.
