Ariel Deitcher, a Senior Software Engineer at GitHub, shares his journey of contributing to open source projects, detailing the challenges and lessons learned along the way. Initially overwhelmed by the vastness of open source, Deitcher found it difficult to find a suitable project and struggled with self-confidence, leading him to defer his open source contributions. His opportunity arose while working at GitHub, where he contributed to the GitHub CLI, addressing technical debt in the merge command and integrating support for the Merge Queue feature.
