Jdmarmen
During a three-month period, José David Marmen developed and modernized core battery management features in the HyperloopUPV-H8/adj repository. He built foundational BMSL integration, overhauled data handling for Direct Current Low Voltage (DCLV) packets, and improved state machine observability to enhance system reliability and future scalability. Using C and C++, he refactored code for maintainability, introduced nanosecond-level measurement precision, and streamlined packet structures to support energy management and reduce technical debt. His work included removing obsolete functionality, fixing sensor accuracy, and standardizing communication protocols, demonstrating a deep understanding of embedded systems, data structures, and backend development challenges.
