PROFILE
Matthew Woehlke
Matthew Woehlke contributed to the RobotLocomotion/drake repository by engineering robust build and packaging workflows that improved cross-platform reliability and reproducibility. He modernized Python dependency management using PDM, implemented isolated virtual environments, and streamlined packaging for both macOS and Linux. Leveraging skills in Python, C++, and shell scripting, Matthew addressed environment-specific build failures, enhanced CI stability, and upgraded solver integrations such as MOSEK. His work included refining documentation generation with Sphinx and regular expressions, updating dependency pinning for multi-version compatibility, and optimizing artifact management. These efforts resulted in more maintainable, secure, and scalable build systems across the project.

Oct 1, 2025October 2025 — Drake (RobotLocomotion/drake) monthly summary focused on packaging and build reliability. Key feature delivered: dependency management modernization in the setup directory, upgrading Python package dependencies to latest stable versions and implementing per-Python-version pins in lock/build files to ensure compatibility and security across supported Python versions, enabling reproducible builds and reducing risk from outdated packages. Committed changes include upgrades and per-version pin generation (commits 7ee3561134a2c420da234bf94f6ddd70f64c5c58 and a9e10a77f5fdfbb83ecbc8da7a117ad35b3fd620). Major bugs fixed: none reported in this scope. Overall impact and accomplishments: strengthens security posture and build reliability across Python versions, reduces maintenance burden, and improves CI stability and developer onboarding through reproducible builds. Technologies/skills demonstrated: Python packaging, virtual environment management (venv), dependency pinning, per-version lockfile generation, and multi-version compatibility.

Jul 1, 2025In July 2025, delivered targeted MOSEK solver integration upgrades for Drake, alongside packaging refinements that streamline deployment, reduce distribution size, and improve license handling. The work focuses on upgrading MOSEK to 11.0.24, removing x86 macOS support, enabling lazy loading of MOSEK in Python wheels, and conditionally excluding MOSEK license files for stub builds to simplify packaging and deployment across supported platforms.

Apr 1, 2025April 2025: Improved cross-environment build reliability for Drake by ensuring diffutils is present across AlmaLinux and Ubuntu Jammy/Noble. Updated package lists to include diffutils, guaranteeing the diff command is available for patch-applying processes and reducing environment-specific build failures. The work is captured in commit d6209b85e28141d589c18f238ce959c2e0c7525b ('Add explicit requirement for diffutils (#22903)'), contributing to more reproducible and stable downstream builds across CI/environments.
