Worked on the olympus-robotics/hephaestus repository, delivering features focused on reliability, observability, and correctness in C++ systems programming. Built and refactored a robust spinner component lifecycle state machine, introduced hardware fault handling with custom exceptions, and enhanced error logging for traceability. Developed time-based control and telemetry using std::chrono, implemented RFC 9562-compliant UUID v4 generation and hashing, and extended protobuf serialization to container types. Emphasized compile-time computation, type safety, and unit testing throughout. Leveraged technologies such as C++, Protocol Buffers, and Abseil to improve maintainability, performance, and integration, while maintaining a strong focus on code quality and modular design.

Mar 1, 2025March 2025 performance summary for olympus-robotics/hephaestus: Delivered three updates across features and bug fixes with a focus on modularity, correctness, and API safety. Key outcomes: refactored Spinner Component State Machine for explicit states and modularity; fixed bounds serialization by adding missing include; improved API correctness by making StopWatch elapsed methods const. Results: increased maintainability, reduced risk of side effects, and more reliable timing and bounds handling in the proto module. Technologies demonstrated: C++, header/module refactoring, const-correctness, state machine design, and serialization/module boundary fixes.
