Worked on the mermaid-js/mermaid repository to improve cross-platform development workflows by addressing both technical consistency and onboarding efficiency. Used shell scripting and Docker to enhance the local development script, adding clearer commands and a quick-start guide that streamlined setup for new contributors. Addressed end-of-line inconsistencies by standardizing line endings in the .gitattributes file, ensuring reliable collaboration across different operating systems. Leveraged version control best practices with git to maintain code quality and repository hygiene. The work focused on reducing developer confusion and setup time, resulting in a more maintainable and accessible development environment for the team.
