● Group Manager - Manager of a diverse team of 50+ managers and software engineer ICs focusing on camera control, display, calibration, and program management working on Microsoft AR products. ● Reliability - Corrected IVAS program software reliability issues by instituting a rigorous Failure Mode and Effects Analysis and creating both short and long term roadmaps to fix deep technical debt. Instituted regular risk management reviews. Reliability increased by 2 orders of magnitude. ● Device Production - Put in charge of correcting yield problems in production of IVAS units. Collaborated effectively with diverse cross functional teams across Microsoft to increase First Pass Yield from 30% to 70%. ● Open Source - Collaborated with open source maintainers to fix dozens of code scanning and security issues. ● Security and Compliance- Led core system code through first Security Technical Implementation Guides (STIG) compliance. Enabled automated code scanning with tools such as Fortify, binskim, credscan, and CodeQL. ● Third Party Engagement - Drove software engagement with chip manufacturers such as Qualcomm on HoloLens 2 and IVAS programs. Worked closely to fix 100+ code scanning and reliability software issues. ● Software Planning and Execution - Managed platform software planning and releases. Deeply involved in software branching and repository structuring. Delivered 10+ software releases for both IVAS and HoloLens 2. ● Communication - Held weekly and biweekly team meetings where I presented current program goals and priorities and what the team progress was. Sent regular mails across the organization to ensure everyone was informed on program changes. Internal poll scores on communication increased 30 points. ● Previously led the delivery of BSP customization, board bring-up, power/thermal/perf mitigation, and security/compliance for 3+ products, driving productivity for a team of 10+

● Engineering Leader - Championed multiple roles including system architect, platform subsystem lead, and the software technical lead for 100+ hardware and software engineers on the Prime Air drone program. ● Software Architecture - Architected and implemented from scratch the safety critical application programming model including process definition, thread priorities, interface definitions, and system performance KPIs. ● Technical Roadmaps - Created both short and long term technology roadmaps across a highly matrixed organization. Worked closely with Directors and VPs to continually update. ● Operating Systems - Selected and configured OSes for functions such as navigation, flight control, and mission management. Partnered with external companies to customize VxWorks and Yocto Linux BSPs. ● Software Manager - Managed a small team focusing on device drivers such as CAN Bus and Ethernet. Personally wrote 5+ software sensor drivers spanning FreeRTOS / VxWorks / Yocto Linux for ARM SoCs. ● Data Processing - Designed an automated data pipeline that automated log extraction and KPI review using Python running in a Docker container and plotting tools such as Bokeh and Jupyter. Started up Jenkins server and incorporated AWS Batch and SQS to automate MATLAB control system gain tuning. ● Software Development Life Cycle - Developed first business unit wide software design, coding, and quality standards. Trained hundreds of Prime Air employees on software certification with DO-178C and supplements. Contracted external DER to ensure independent auditing of software processes.

● Java Development - Coded 5+ Java features for autonomous aerial vehicle mission planning. Improved both coarse and fine routing of graph based planning software. ● Customer and Partner Integration - Represented BAE Systems in integration and planning meetings with other defense entities such as Northrop Grumman, Raytheon, Lockheed Martin, Mitre, and USAF. Visited partner Riverside Research weekly to ensure that engineering features were meeting expectations. Met with USAF personnel to ensure user feedback was incorporated into the product. ● Continuous Integration - Bootstrapped and administered Jenkins instance, integrated code coverage for nightly and weekly tests, and added in Fortify code scanning for security. ● Distributed Message Passing - Set up and maintained XML based message passing systems such as ActiveMQ. Messages would pass between a clustered backend system written in Java through the queue and into a thin UI layer written in C#. In charge of updating and upgrading XML schema when necessary. ● Virtual Machines - Provisioned and deployed virtual machines running Linux on Microsoft Server 2012. Configured ports, resource allocation, and monitored KPIs such as RAM and CPU loading. ● Security Clearance - (currently inactive).
