During their two-month engagement, Alexander Lerach developed and enhanced CI workflows for the PX4/PX4-Autopilot repository, focusing on firmware size analysis and pipeline reliability. He implemented an automated workflow using Python scripting, YAML, and GitHub Actions to analyze firmware size changes with the bloaty tool, providing immediate feedback on flash usage directly in pull requests. Lerach also stabilized the CI pipeline by standardizing Docker-based build environments for NuttX targets and updating flash analysis to support newer GCC toolchains. His work improved build consistency, accelerated feedback loops, and enabled more accurate firmware validation, demonstrating depth in build systems and CI/CD automation.
In May 2025, delivered CI pipeline stabilization and firmware analysis improvements for the PX4-Autopilot project targeting NuttX. Consolidated three CI/workflow enhancements to stabilize builds, improve firmware size reporting with newer GCC toolchains, and ensure reliable failsafe simulations.
