Worked on the valhalla/valhalla repository, focusing on build system optimization, code maintainability, and reliability over a five-month period. Delivered features and fixes in C++ and SQL, including memory layout stabilization for OSMAccessRestriction, comprehensive code hygiene cleanups, and refactoring of include directives to reduce compile times. Improved build reliability by reorganizing logging, cleaning up namespace usage, and standardizing changelog documentation. Addressed cost calculation robustness for multimodal transportation by refining random distribution logic and expanding unit tests. These efforts enhanced developer productivity, reduced regression risk, and ensured more accurate, maintainable, and scalable code across the project’s evolving codebase.
