Worked on the ziglang/zig repository to enhance codebase consistency and maintainability by refactoring import statements for Base64 and Hex codecs in codecs.zig. Focused on aligning import naming with project conventions, the developer converted imports to lowercase, improving readability and reducing onboarding friction for future contributors. This effort, implemented using Zig and backend development skills, aimed to standardize codec handling and support more stable CI checks. No major bugs were addressed during this period, as the primary objective was to streamline the codebase for future development and facilitate easier integration of additional codecs or related backend features.
