About

Technical Lead with 12+ years of experience building AI-enabled platforms, large-scale consumer systems, and enterprise engineering infrastructure at Microsoft and Adobe. I specialize in AI-assisted software engineering, platform systems, and large-scale architecture. At Microsoft, I’ve led initiatives spanning AI-driven code modernization, developer productivity and release platforms, and high-impact consumer experiences across Windows, Web, and Xbox, used by millions globally. My work focuses on applying LLMs, automation, and strong system design to reduce technical debt, improve reliability, and enable safe, repeatable change across complex, distributed production environments. I’ve designed platforms that balance scale, governance, and engineering velocity, ensuring AI-powered workflows are production-ready and trustworthy. I hold multiple granted patents and enjoy technical leadership, mentoring engineers, and collaborating across functions to turn complex problems into scalable, long-lasting platforms. I’m particularly interested in opportunities involving AI-first platform systems, distributed software, and global-scale engineering challenges.
