PROFILE

Leland Sion

Leland Sion developed and integrated a Battery Management System for the UVicSatelliteDesign/COMP_SLIP-OBC repository, focusing on reliable battery data monitoring and persistence. Over three months, he implemented modules in C for battery initialization, voltage, current, and temperature readouts, and state of charge and health calculations, using microcontroller programming and embedded systems techniques. He refactored code for maintainability, migrated BMS logic to dedicated interfaces, and ensured data integrity by fixing STM32H7 flash memory write intervals. Leland also improved repository hygiene with Git and .gitignore management. His work emphasized robust data handling, code clarity, and long-term maintainability for mission-critical firmware.

May 2025 monthly summary for UVicSatelliteDesign/COMP_SLIP-OBC: Focused on strengthening battery data persistence and code quality. Implemented a critical fix to the flash memory save logic for STM32H7 using correct 128-bit write intervals, resulting in more reliable battery data persistence. Refactored ADC handler names for clarity and resolved minor battery function issues to improve maintainability and reduce risk of future incidents. These improvements were delivered with a strong emphasis on reliability, data integrity, and long-term maintainability.
