Worked on targeted deprecation cleanups and API hygiene improvements across the snyk/code-client-go and snyk/go-application-framework repositories. Focused on removing deprecated fingerprints and types from both Go code and OpenAPI specifications, using Go and YAML to streamline data transformation logic and reduce technical debt. The approach preserved existing behavior while eliminating legacy elements, which helps prevent misinterpretation of outdated data and reduces the risk of future breakages. These changes improved maintainability and laid the foundation for future deprecations and cleaner API surfaces, demonstrating a methodical approach to code refactoring and API development within a short, focused development period.
