PROFILE
Ali Naqvi
Ali Naqvi developed and enhanced embedded firmware and driver modules for the MacRover/maxwell repository, focusing on the VIPER platform’s system integration and reliability. Over four months, Ali architected and generalized the MCP3221 driver for STM32 microcontrollers, transitioning communication from timer-based to UART and improving voltage and current sensing accuracy. He overhauled the VIPER CAN bus protocol, introducing robust message handling and ROS-ready build scaffolding using C++ and CMake. By centralizing voltage status reporting and refining data flow, Ali improved maintainability and observability. His work demonstrated depth in embedded systems, driver development, and hardware interfacing, addressing platform scalability and diagnostic needs.

Mar 1, 2025March 2025 – MacRover/maxwell: Delivered a focused data reliability and maintainability enhancement for the Viper subsystem. Implemented Viper System Input Voltage Handling and Status Centralization, centralizing voltage data in ViperStatus to improve monitoring, reporting, and downstream integration. Fixed critical decoding logic by correcting the decode_can_msg assignment (state vs. status) and migrated the float input voltage from CardStatus to ViperStatus. Updated the data path to send messages from state to reflect the new centralized model. These changes reduce data duplication, improve accuracy of voltage reporting, and simplify future extensions, delivering measurable business value in system reliability and observability.
