Worked on documentation improvements for the shepazon/aws-doc-sdk-examples repository, focusing on enhancing contributor onboarding and maintainability. Updated the CONTRIBUTING.md file to reference Wikipedia for DRY and SOLID principles, ensuring that guidance for contributors is standardized and based on neutral, widely-recognized sources. Utilized Markdown for documentation updates and collaborated through Git-based workflows, including pull requests and commit management. The work addressed ambiguity in contributor instructions and aligned documentation with best practices for open-source projects. Demonstrated skills in documentation maintenance, adherence to contribution standards, and effective use of version control systems to support a more accessible and sustainable codebase.
