Work History

March 2026

8 Commits • 3 Features

Mar 1, 2026

March 2026 focused on delivering advanced trajectory optimization features using ACADOS MPC, stabilizing CI and build environments, and improving integration readiness across Autoware repositories. Key outcomes include new MPC-related parameters in the Path Optimizer, acados-based MPT enhancements with corrected A/B switching, and CI/docker improvements to reduce churn and speed up validation.

February 2026

4 Commits • 3 Features

Feb 1, 2026

February 2026 highlights focused on accelerating setup reliability and development environment consistency across Autoware projects. Implemented recursive VCS import for nested repositories, enabling complete dependency fetch during setup, and migrated Rust toolchain provisioning to rustup via Ansible for improved version management. Documentation was updated to clearly guide users on the --recursive flag for vcs import, reducing onboarding friction and setup errors. These changes strengthen build stability, CI/CD readiness, and developer productivity across autoware foundation repositories.
