Contributed to code quality and documentation improvements across two open source repositories, focusing on maintainability and onboarding. In the piplabs/story-geth project, addressed technical debt by removing redundant comments from the core virtual machine logic in Go, enhancing code readability without altering functionality. For yaklang/yakit, refined the English README-EN.md using Markdown, correcting punctuation to improve clarity and consistency for new users. The work emphasized code cleanup and editorial standards, supporting faster onboarding and reducing future support needs. Throughout both projects, maintained alignment with repository standards and prioritized long-term maintainability, demonstrating attention to detail in both code and documentation practices.
