Szabolcs Fuzi developed a GraphQL 'courses' endpoint for the instructure/canvas-lms repository, enabling efficient retrieval of accessible courses by IDs or SIS IDs. He focused on backend development using Ruby on Rails and GraphQL, implementing robust input validation and enforcing per-request limits to safeguard against oversized queries. This approach improved API reliability and scalability while simplifying client-side integration for administrators and SIS systems. Although the work spanned a single feature over one month, Szabolcs demonstrated a solid understanding of GraphQL API design and commit-driven development, delivering a targeted solution that enhanced data accessibility and developer productivity within the platform.
