Worked on enhancing reliability and maintainability across the PX4-Autopilot and mavlink repositories, focusing on both package management and telemetry improvements. Addressed package installation issues in PX4-Autopilot by pinning the setuptools dependency, which resolved a ModuleNotFoundError and improved installation stability. Refactored the computeReturnAltitude function to streamline its API, removing unused parameters and standardizing accessors for better code clarity. In the mavlink repository, extended the CELLULAR_STATUS message by adding a SINR field, enriching cellular telemetry data. Utilized C++, Python, and XML, applying skills in code maintainability, communication protocols, and software refactoring to deliver targeted, cross-repository enhancements.
