Xander Moffatt
Over seven months, Xavier Moffatt engineered robust LTI integrations and API enhancements for the instructure/canvas-lms repository, focusing on reliability, accessibility, and data integrity. He delivered features such as per-client OAuth throttling, cross-shard deployment safety, and improved Canvas Apps navigation, using Ruby on Rails, TypeScript, and React. His work included backend data modeling, database migrations, and frontend UI/UX improvements, addressing both user experience and operational efficiency. By implementing caching optimizations, error handling, and feature flag-driven automation, Xavier ensured scalable, maintainable solutions that reduced manual steps, improved security, and aligned complex data lifecycles across multi-tenant educational environments.

Sep 1, 2025Monthly summary for 2025-09 for instructure/canvas-lms: Delivered two major areas focused on business value and data integrity. (1) Backend features enabling per-client OAuth overrides through a new OAuthClientConfig model, with per-client request throttling overrides and caching optimizations to improve fairness and reduce backend pressure. (2) Critical data integrity fix for LTI Registration state when a DeveloperKey is deleted, including a backfill to ensure registrations reflect the deleted workflow state. Overall impact: improved client-specific OAuth behavior, stronger protection of backend resources via throttling, and ensured lifecycle consistency across DeveloperKey and LTI Registration states. Technologies/skills demonstrated: backend data modeling (OAuthClientConfig), caching optimizations, data migrations/backfills, lifecycle governance, and security-conscious design.
