Worked on the myparcelnl/pdk repository to enhance the reliability of the CI/CD pipeline by addressing compatibility issues in the automated code-quality tooling. Focused on stabilizing continuous integration processes, the developer resolved a persistent bug by pinning PHPStan, a static analysis tool, to version 1, ensuring alignment with the project’s PHP version constraints. This change eliminated CI failures caused by incompatibilities with PHPStan v2, directly fixing issue INT-774. The work involved PHP and DevOps practices, emphasizing maintenance and operational stability over new feature development. Throughout the month, efforts centered on improving automated checks and reducing risks from tooling mismatches.
