Rcschwartz18-lgtm
Worked on the CU-Robotics/firmware repository to modernize and enhance the firmware’s profiling subsystem, focusing on observability and performance analysis for embedded systems. Overhauled the legacy profiling code by introducing a structured profiler with begin, end, and print capabilities, conditionally compiled using the PROFILE macro to minimize production overhead. Refactored internal data structures and improved instrumentation, enabling more accurate and readable performance measurements. Addressed reliability by fixing delta time calculations and refining profiling loop handling, which improved measurement accuracy and stability. Utilized C++ for firmware development, code refactoring, and debugging, resulting in faster optimization cycles and reduced technical debt.

Aug 1, 20252025-08 monthly summary for CU-Robotics/firmware focusing on engineering improvements that deliver measurable business value. This period centered on modernizing the firmware's observability through a Profiling System Overhaul, removing legacy profiling code, and introducing a clear, structured profiler with begin, end, and print capabilities. The new profiler is conditionally compiled via the PROFILE macro to minimize overhead in production builds while enabling deep performance analysis during debugging and optimization cycles.
