Worked on TobikoData/sqlmesh to deliver enhancements to the lineage DAG UI, focusing on improving layout customization and visual clarity for data lineage exploration. Implemented draggable and resizable DAG nodes using React and JavaScript, allowing users to tailor the interface to their workflow. Added tag-based color-coding to visually differentiate lineage segments, which supports faster debugging and more intuitive navigation. All changes were delivered through well-documented, signed-off commits, reflecting attention to code quality and collaborative standards. The work demonstrated practical application of front end and full stack development skills, with a focus on usability and maintainability rather than bug fixing.
