PROFILE

Arnaud Mallen

Worked on stabilizing and modernizing CI/CD pipelines and build systems for the swift-nav/libsbp and swift-nav/rules_swiftnav repositories, focusing on release reliability and developer productivity. Addressed cross-language workflows by updating runner configurations, container images, and artifact generation, using technologies such as Docker, Rust, and GitHub Actions. Delivered new SBP protocol support with comprehensive documentation and tests, while also migrating CI infrastructure to Ubuntu 24.04 to resolve failures and reduce release risk. Improved build configuration by suppressing non-actionable compiler warnings, resulting in clearer test results and faster triage. Emphasized maintainable automation, robust testing, and consistent release processes throughout the work.

September 2025: Focused on CI/build stability for swift-nav/rules_swiftnav. Delivered a build configuration improvement to suppress -Wstack-protector warnings in CI by removing the stack protector warning flag from the build configuration. This reduces CI noise, makes test results clearer, and accelerates triage by ensuring only actionable warnings are surfaced. No major bugs fixed this month; maintenance work prioritized CI hygiene and consistency. Overall impact: improved developer productivity, more reliable automated checks, and clearer readiness signals for releases.

2025-08 Monthly Summary — swift-nav/libsbp. Key features delivered: SBP MSG_SSR_FLAG_HIGH_LEVEL_DEP_A support (SBP 3002) with updated documentation and tests to reflect the new message and its handling within the library. Major bugs fixed: CI pipeline reliability improved by migrating to ubuntu-24.04 runners, and removal of deprecated ubuntu-20.04 runners, addressing failures/timeouts and restoring healthy libsbp CI pipelines. Overall impact and accomplishments: more reliable CI feedback and faster validation of changes, reducing release risk for SBP updates and improving test coverage for new message handling. Technologies/skills demonstrated: CI/CD workflow modernization (Ubuntu 24.04), Linux/CI pipeline maintenance, SBP protocol updates, documentation and test development, and Git-based collaboration. Commits (examples from this work): Remove deprecated ubuntu-20.04 runners [OI-3101] (#1490) — bcd9e567861c8dd71b658e5e2998e978cf5c9b32; New High Level Flag Message (3002) [OI-3101] (#1487) — 0eaf16cac4dfc026c14048f7e6a9455a68fb81e3.

In July 2025, I focused on stabilizing the CI/CD pipelines for swift-nav/libsbp to improve release reliability, artifact reproducibility, and cross-language workflow consistency. The work addressed Rust, artifact generation, and Python workflows, with updates to runner configurations and container images to ensure compatibility and stability. I also enhanced logging and assertion messages to expedite debugging and root-cause analysis. This effort reduces release risk, shortens build and deploy cycles, and lays groundwork for more automation and faster feature delivery across the project.
