* Owned shared code used by Workstation, Fusion, VMRC, & View products for interfacing with virtual graphics and screen device to handle full screen, multiple monitors, & showing guest windows on the host desktop (“Unity”).* Led development for Fusion Unity mode; maintained, enhanced, fixed bugs, assisted users, and developed new features; helped other teams to develop features and share code with cross-functional teams.* Wrote specs for new features, drove feature team meetings and development with other teams, handed features off to QA, assisted in testing and QA cycles, helped community forum members, fixed bugs, and delivered features.* Helped to maintain C++ common user interface libraries, which bridge lower level C/C++ to higher level Cocoa code.* Re-wrote Objective-C-only code in C++ so it could be shared with other platforms.* Worked across products and platforms to fix Unity bugs that affected Fusion, Workstation, Player, and View.* Developed high-resolution support for Unity mode, enabling users to take advantage of Retina and high-DPI monitors.* Drove the investigation, analysis, design, and implementation to address fundamental incompatibilities between VMware's Unity mode and Microsoft’s new “Metro” style applications, introduced with Windows 8.* Mentored the Mac View team; helped them refactor, reuse and cleanly share common code when implementing Seamless Windows and other features.* Participated on a five-member team at the VMware Take2 Hackathon (2-day event) and worked to implement a “synthetic block device” to build a block based image of a directory structure, which was awarded second prize.* Helped implement remote VM support and assisted in the removal of “local VM only” assumptions from the code.* Devised support for Fusion to use shared USB Arbitrator service, allowing Fusion and View to share USB devices.* Improved Workstation’s and Fusion’s Unity feature to increase reliability and better support Windows 8 and 8.1.

Palo Alto, Ca, Us

* Shaped the user-visible portions of Linux Workstation and Player; added features, fixed bugs, and enhanced the users’ experience.* Collaborated with Open Source development communities for Compiz, KDE, and XFCE4 Linux Window Managers; helped implement _NET_WM_FULLSCREEN_MONITORS EWMH spec feature addition.* Led the cross-platform and cross-team work to re-architect the virtual graphics/screen API for Workstation/Player, allowing our products to show live VM thumbnails and improve performance and memory use in all modes. Formalized the new API into a common layer of code used by Linux, Windows, and OS X products.* Wrote specs for new features, drove feature team meetings and development with other teams, handed features off to QA, assisted in testing and QA cycles, helped community forum members, fixed bugs, and delivered features.* Enhanced and extended the common code infrastructure supporting Unity feature, and the video architecture that was used by Unity and other display modes for multiple products, across different host Operating Systems.
