PROFILE
Zachmahan
Over eight months, contributed to BrownSpaceEngineering/PVDXosV2 by building core embedded systems features, including a magnetorquer control framework, CCSDS Space Packet Protocol implementation, and device health monitoring interfaces. Focused on modular C and C++ development, the work emphasized maintainability through robust documentation, Doxygen integration, and Makefile management. Enhanced system reliability with power-on self-tests, logging infrastructure upgrades, and custom assertion-based unit testing, supporting real-time and hardware-interfacing requirements. Regularly improved code organization and documentation, streamlining onboarding and CI workflows. The technical approach prioritized test-driven development, protocol design, and clear separation of concerns, resulting in a scalable, maintainable embedded software foundation.

Feb 1, 2026February 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.
