Worked on the ansible/receptor repository to enhance build system flexibility by updating the Makefile, making the ARCH variable optional and defaulting it to amd64 when unset. This adjustment streamlined the build process for contributors and continuous integration environments by removing the need for manual architecture configuration. The solution, implemented using Makefile and build systems expertise, improved developer onboarding and stabilized builds across different platforms. By referencing issue #1299 and maintaining clear commit traceability, the work laid a foundation for future multi-architecture support, ultimately increasing release velocity and reducing setup friction for both new contributors and automated CI pipelines.
