• Landed on the ground running and rapidly brought up full Falcon sensor development, build and testing environment for MacOS, and later for Windows and Linux. Used this understanding to gain deep insight that was needed to convert a complex sensor tampering test from the legacy testing framework to the leading edge tooling, involving restructure and refactoring to new APIs. Focused on deep understanding and contributions to next generation generative build system and identification of key areas for productivity and quality enhancement as well as training for new members of the team. Effectively participated in many high-level discussions and planning for increased engineer productivity, and successfully refactored and deployed a major critical path merge tool used by the entire sensor engineering team.

• Ramped quickly on existing SaaS and on-premise time series database code (C, C++, Lua) and began contributing many fixes, tests, improvements and new features. Developed new features with complex multi-threaded code while reusing and working with legacy code. Debugged difficult customer crash, memory and functionality issues (including intermittent issues) using multiple debugging techniques and creation of new tools and techniques. Overhauled and improved build, increased speed by 2x, and improved CI and manual build/test/debug scenarios to add Test Stability, Memory Debug, and Unreleased Shared Library scenarios, Run Static Analysis, and Run Tests Against Dev Cluster. Mentored other engineers and improved team productivity, often getting them unstuck quickly. Worked excellently with colleagues, stakeholders, and coworkers actoss teams as well as customers.
• Key Achievements:
• ▪ Added support for high-speed deletion of old or unwanted time series data, interleaving with and enhancing/reusing existing code.
• ▪ Developed and integrated large feature set to introduce efficient sharded storage for histogram data side-by-side with raw numeric storage.
• ▪ Sped up data recovery/reconstitute by 4x by greatly reducing data movement and copying.
• ▪ Provided an interpreter/translator for PromQL query language to Circonus Analytics Query Language
• and took over maintenance of these data analysis and graphing modules.
• ▪ Developed and open-sourced LeakLite as a prototype for a minimal overhead web-centric real time memory usage monitoring and leak debugging tool.

• Took the baton early and exceeded expectations on quality assessment and dashboard initiatives, including code coverage analysis as well as automation of reports from static code analysis, compiler warnings, and automated test status and performance, providing actionable data to engineers and managers. Follow-up on these projects provided the foundation for tooling improvements across the company. Performed maintenance and enhancements on old tests and developed completely new tests for human interface devices and interfaces across all classes of Apple devices and with new devices such as the new HomePod and Mac Pro. Gained and demonstrated expertise in build as well as test hardware and software, and in tool development and innovative, high coverage testing techniques. Implemented enhancements to test automation GUI to speed up interpretation of live test output and assist in debug.
• Key Achievements:
• Repeatedly handled required test changes across a number of automated tests to bring them all back to green in preparation for MacOS High Sierra and other 2017 OS releases.
• Developed new tests to provide coverage for the HomePod display and touch panel, and for the innovative new architecture of the new Mac Pro.
• Created a new automated test status and performance tool to automate generation of test reports by consolidating data obtained from multiple REST APIs. This tool eliminated time spent by engineers to create these reports, made intermittent failures more visible and provided concrete actionable metrics of test and OS health to engineers and management.
• Cleared hurdles in obtaining streamlined automated code coverage reports down to source line level, setting in place the foundation for code coverage to be added to Stash and XCode.

• Took on leadership roles from the research and planning stages through programming and testing as well as documentation and training on multiple parallel projects. Earned many awards for going above and beyond to deliver solutions, including closed-chassis debug, silicon debug on Haswell Xeon, and MDO Innovation Day Award (April 2016). Collaborated effectively with managers, coworkers and customers to develop creative, forward-looking solutions. Rapidly diagnosed and addressed software and hardware defects using innovative debugging techniques and deep low-level knowledge. Performed requirements gathering, architectural planning, and GUI/workflow design with actual end users. Initiated proof of concept and full implementation of solutions using infrastructure, tools and virtualization to improve programmer productivity. Mentored and taught groups and individuals on subjects ranging from defect prevention, visibility and debugging, Agile/Lean, the seven sources of waste, 5 Choices for Extraordinary Productivity to Processor Architecture and Installation/Packaging.
• Key Achievements:
• Overcame obstacles in debug and test scenarios in simulation and on actual hardware using knowledge of tools, coding strategies and other techniques, while training other developers.
• Participated in enhancements and debugging of Dragon Intel x86 core manufacturing tests.
• Developed and debugged a BIOS EFI modules, worked on debug and board schematics as well as BIOS source code, built BIOS from source.
• Gathered requirements and lobbied for software and hardware support from other teams, brought stakeholders to the negotiation table, and drove effective execution of specific features and infrastructure necessary to build a solid foundation.
• Pulled together training program, videos, and wiki landing zones for new and old team members, centralized and organized software and documentation assets, served as a trainer and instructor as well as a mentor to the rest of the team.
