Worked on the facebook/buck2-prelude repository to deliver FoundationModels Framework Support, focusing on build system configuration using Starlark. Added version information for the FoundationModels framework to the Apple framework versions configuration, enabling the build system to accurately identify and utilize FoundationModels across various Apple operating systems. This technical approach improved build reliability by ensuring that essential metadata is present, which reduces misidentification and cross-OS compatibility issues. The work laid the foundation for smoother downstream integration of FoundationModels and contributed to more stable continuous integration processes. Demonstrated skills in build system configuration, Apple framework metadata management, and targeted code changes.
