• Flight Software Development Intern

  • May 2017 - Aug 2017

  Implemented enhancements, new features, bug fixes, and automated testing for propulsion related Crew Dragon Flight Software. This includes adding features to detect and respond to propellant leaking in Draco engines, to detect multi-fault leaks, and to communicate faults to GNC code appropriately. Worked to simplify and refactor existing systems as requirements changed. Implemented a configuration generator system for Crew Dragon that will reduce future maintenance burden.

• Flight Software Platforms Intern

  • May 2016 - Aug 2016

  Created, presented, and implemented a plan to upgrade the flight software build system. This upgrade allowed building flight software using a "clean" interface to the platform installed on the target. Upgraded the toolchains used to build the platforms and the flight software to GCC5.3 using the MUSL libc. The libc upgrade included changes to the assembly in MUSL to support the particular PowerPC variant SpaceX uses.

• Flight Software Test Intern

  • May 2015 - Dec 2015

  Planned, tested and executed migration from SVN and Trac to Git and JIRA. Investigated side effects of Linux Kernel updates to Hardware Out of the Loop Testing (HOOTL) infrastructure. Improved overall robustness of HOOTL and Hardware in the Loop test infrastructure. Implemented continuous integration for test infrastucture. Added ability to telemeter data to the test driver. Wrote and implemented test plans for flight software components such as "output agreement" and "Firmware Comm." Planned, tested and executed migration from SVN and Trac to Git and JIRA.
