Worked on the supabase/supabase-py repository to refactor the SupabaseAuthClient, focusing on stabilizing authentication client initialization across both asynchronous and synchronous code paths. Leveraged object-oriented programming principles in Python, utilizing super() for consistent base class initialization, which improved code readability and reduced the risk of initialization errors. Updated the Makefile to map asynchronous code to its synchronous counterparts, clarifying the build process and minimizing drift between different execution paths. This work enhanced maintainability and set a foundation for faster feature delivery, demonstrating skills in build automation, Python, and refactoring while addressing reliability and maintainability within the codebase.
