• As Director of Engineering in Azure Core, I lead a globally distributed organization of managers, software and service engineers focused on delivering world-class infrastructure for next-generation computing. I manage the team driving innovation across Azure Supercomputing, exabyte-scale storage systems, and multi-tier archival solutions.
• My organization builds and operates the foundational services powering Microsoft’s most advanced high-performance computing (HPC) platforms - enabling mission-critical workloads across science, research, and AI. We specialize in scalable systems design, high-throughput data pipelines, and resilient storage architectures tailored for supercomputing performance.
• Key focus areas include:
• End-to-end engineering ownership for HPC storage and archival stack
• Global team leadership spanning development, operations, and support
• Cross-functional collaboration with hardware, networking, and AI teams to optimize compute/storage integration
• Driving technical strategy, execution excellence, and operational maturity at scale
• I'm passionate about building high-trust, high-impact teams that push the boundaries of cloud infrastructure.

• Led engineering across multiple mission-critical Azure offerings, including Azure Large Instance (ALI) and Azure VMware Solution (AVS). Built and scaled global teams across the U.S. and India, delivering cloud infrastructure for high-performance computing, ML workloads, and enterprise migration.
• As the founding head of ALI, I drove the product from inception to over $100M in annual revenue—powering Microsoft and OpenAI’s ML platforms with Kubernetes-based GPU clouds, and delivering industry firsts in persistent memory and ultra-large RAM instances (up to 64 TB). Enabled top healthcare and retail organizations to run latency-sensitive, high-availability systems on Azure.
• For AVS, I led the infrastructure, core platform, and secure deployment into FedRAMP and HIPAA-compliant environments. Drove CI/CD, global scale-out, and core engineering systems to support critical enterprise cloud workloads.

• Developer and tech-lead in the .NET runtime team. Built generational garbage collector from scratch, worked on CLR performance, memory sub-system, platform abstraction, loader/binder. Helped with the early work of making .NET CoreCLR work on Linux, Symbian and other non Windows operating systems and run on ARM, MIPS, SH3 and other non intel CPUs. Was responsible for making multiple performance optimizations and novel implementation to make .NET run on resource constrained (low memory, low CPU, battery powered) devices. These features allowed Windows a primarily desktop OS at that time to be successfully launch on Phones and Tablets and allow .NET to be the primary runtime to power apps on devices not only on Windows, but on Xbox, Symbian phones, set-top boxes, cars etc.
