Worked on the CMBAgents/cmbagent repository to initiate the Gemini-3 Preview feature, establishing the groundwork for future feature parity and delivery. The approach involved creating a dedicated feature branch and opening a draft pull request to enable early collaboration and incremental integration of Gemini-3 preview functionality. Leveraged Git for branching strategies and workflow management, focusing on minimizing disruption to the mainline while allowing for early validation and risk assessment. The work demonstrated proficiency in collaborative development practices, including the use of draft PRs and isolated feature development. Technologies likely involved include Git, GitHub workflows, and standard software engineering practices.
