Worked on backend development and refactoring for the LiU-SeeGoals/controller repository, focusing on improving the FastBrainGO instruction handling logic. The primary effort involved removing unimplemented instruction types from the instructionToAction function, which reduced dead code paths and simplified the overall control flow. By eliminating these unused instruction paths, the changes also reduced noisy logs, making production monitoring and debugging more manageable. This targeted cleanup enhanced the stability and maintainability of the codebase, setting a solid foundation for future feature integration. The work was carried out using Go, with an emphasis on backend reliability and codebase readiness for upcoming development cycles.
