Haydn Li developed two core features for the dstackai/dstack repository over a two-month period, focusing on both user experience and infrastructure efficiency. He implemented public project visibility and participation, allowing non-members to join or leave projects through a new UI while enhancing permissions and visibility settings for secure public and private project management. In addition, Haydn delivered an idle volume auto-cleanup mechanism that automatically purges unused storage volumes after a configurable duration, with safeguards for external and attached volumes. His work combined Python (FastAPI), React, and SQLAlchemy, demonstrating depth in backend development, system design, and database management.
