• Senior Software Engineer

  • Feb 2020 - Present

  Architect for next gen WebRTC stack enabling browser use cases on mobile platforms where standalone app supporting multiple games had issues due to vendor requirements for app store certification. 1 patent granted. Rearchitected GCUpdateTool, a distributed installation tool, unifying code paths for single platform (dev/demo) and multiplatform (customer) so that continuous QA could be efficiently implemented in a small team without dedicated QA. Development Environment: C++ on Windows using Visual Studio. Show less



VMware

• Staff Engineer

  • 2014 - 2018

  For 4 years I led a small team developing a new USB driver stack for vSphere ESXi. As part of this effort I worked extensively with functional and system QE as well as external partners to ensure adequate coverage across the broad set of supported USB devices. In addition I worked to further extend the flash "friendliness" of ESXi so that vSphere can use low cost commodity flash for a broader set of mission critical non performance critical applications such as storage of system boot and core dump images.

• Staff Engineer, Storage

  • 2009 - 2014

  I worked on VMware's Virtual Flash host based flash caching product and shepherded it into the vSphere 5.5 release as vFRC (vSphere Flash Read Cache). This was the only one of three major storage featured that was delivered ontime in the vSphere 5.5 release. Subsequently I worked on the next generation architecture for flash caching on the vSphere host before taking a short-term international assignment with VMware India (Pune office) continuing my prior work on storage management. This work had transitioned offshore and I led a small team to enhance the product which successfully delivered the desired new functionality for the vSphere 6.0 release. Prior to this as part of a small team I designed and implemented a prototype enabling transparent support in vSphere for storing VM images in local and remote blob stores, including both internal and external clouds, and for running VMs directly from the stored images. As indicated previously, prior to working on cloud storage I worked on storage management for stateless vSphere systems (i.e., deployed on hosts with no persistent media). 2 patents granted on storage management, 3 patents granted on virtualization using blob stores with BASE consistency models, and 4 patents granted on flash caching in a virtualized environment.

• VMkernel USB Architect

  • 2005 - 2009

  My initial primary focus upon joining VMware was enabling USB support in ESXi. I served as lead, directing self and 2 other engineers, and the effort ranged from kernel drivers to character device nodes enabling access to USB devices by user mode applications and VMs (aka, USB passthru). I designed a ground breaking mechanism (3 patents granted) to safely share USB devices among VMs while preventing DoS and other attacks on the system. Secondary technical focus areas included entropy generation and delivery and NIST certification of same, setup and management of processor MSRs, and hand optimization of hot path code. 2 additional patents granted on other aspects of USB and virtualization. In my spare time I acted as engineering liaison with a major OEM partner during development phase of ESXi and successfully drove resolution of numerous technical issues to keep the OEM onboard with the ESXi program.

Intel Corporation

• United States
• Semiconductor Manufacturing
• 700 & Above Employee

• Virtualization Researcher

  • 1999 - 2005

  Worked in the Microprocessor Research Lab analyzing the performance characteristics of Virtual Machine Monitors (VMMs) and hardware support for same. Helped design and develop 3 research VMMs as part of a small team (5-6 software developers), 1 of them as lead architect. As lead I designed and developed a hypervisor-style VMM with real-time QoS capable of running COTS multimedia apps and a softmodem on an ultra-fast (microcode-assisted) emulator of VT. 34 granted patents on virtualization.

• Senior Software Engineer

  • 1995 - 1999

  Working in the Intel Architecture Labs I developed methodologies to analyze causes of poor real-time performance in the absence of OS source code access and applied same during Microsoft's development of Windows 98. Successfully evangelized softmodems and helped convert Microsoft to a neutral position on same. Publications: IDF 1998, OSDI 1999, WinHEC 1999 (invited) and RTAS 2002. 4 granted patents on real-time systems and softmodems.
