As a software engineer and lead, I focus on both the near term development and the future of SIG’s ground software, technology and related applications. I have developed ground software with an emphasis on applications integrating with the InControl core product. I have worked sprint-based agile projects and traditional iterative build-based lifecycles. Areas of experience include requirements and early development, schedule planning, EVM, build and deployment, system testing, support of spacecraft integration and test phase including mission simulations and rehearsals, launch support, post-launch ground software activities, and management of teams working these various tasks. My roles have included serving as a Ground Software Lead (post-launch for PSP, mid-development for DART) and two years as Downlink and Data Management CSCI lead, and I am currently serving as the SIG Chief Engineer.
