Zach Mahan developed core embedded software features for the BrownSpaceEngineering/PVDXosV2 repository, focusing on modular control systems, protocol implementation, and robust hardware interfacing. He established the Magnetorquer Control Task Framework and implemented the CCSDS Space Packet Protocol core, using C and C++ to ensure modularity and testability. Zach introduced device health monitoring interfaces and power-on self-test routines, improving hardware reliability and startup diagnostics. He enhanced documentation with Doxygen and streamlined build tooling for Linux compatibility. His overhaul of the logging subsystem, including macro-wrapped logging and unit testing, improved debugging and release stability, reflecting a methodical approach to embedded systems development.

February 2026 (BrownSpaceEngineering/PVDXosV2): Delivered a major upgrade to the logging subsystem, introducing build-time separation between test and debug logs, macro-wrapped logging, and a dedicated unit-testing infrastructure for logging. Also cleaned release builds by removing temporaries revealed through macro expansion and replaced all raw logging calls with wrappers to ensure consistent behavior across configurations. This work enhances observability, debugging efficiency, and release stability, providing a scalable foundation for logging across modules. Impact: Improved issue diagnosis, lower mean time to resolve, and reduced risk of log-related regressions in production releases. Enables more predictable log volumes and clearer separation of test vs. production diagnostics, directly supporting faster feature validation and safer deployments. Technologies/Skills Demonstrated: C/C++ macros and conditional compilation, build-system hygiene, macro-wrapped interfaces, unit testing for logging, and test-vs-production log separation.
