PROFILE
Mysti Lilla
Mysti contributed to the instructure/canvas-lms repository by building and refining backend features that improved content migration, file access security, and system reliability. She implemented feature flags and JWT-based authentication to enhance deployment flexibility and safeguard file downloads, using Ruby on Rails and TypeScript to manage API endpoints and backend logic. Her work included optimizing database queries for admin workflows, centralizing attachment handling, and streamlining asset verification during course copy operations. By focusing on robust testing and configuration management, Mysti delivered maintainable solutions that reduced runtime errors, improved caching, and aligned system behavior with evolving security and hosting requirements.

Work History
October 2025
7 Commits • 1 Features
Oct 1, 2025October 2025: Focused on stability, performance, and security improvements in instructure/canvas-lms. Delivered robust export handling, deduplicated dashboard data calls, streamlined attachment access controls, and secure, cache-friendly avatar URL management. Implemented targeted tests to verify behavior across edge cases (missing file references, prefetched data usage, cross-shard avatars). These changes reduce runtime errors, lower API load, and improve cache effectiveness and data privacy. Tech stack highlights include Ruby on Rails, JWT handling refinements, and comprehensive unit/integration tests (RSpec).

Aug 1, 2025Monthly summary for 2025-08: Delivered reliability improvements and configuration hardening in instructure/canvas-lms focusing on InstFS JWT access and attachment association defaults. Implemented JWT fallback URL for InstFS to handle domains not configured, updated URL generation and routing through controllers and helpers, and removed the original_url from InstFS to simplify access paths. Enabled safer default for the attachment association feature flag and fixed YAML formatting in verifiers.yml. These changes reduce support incidents, improve security posture, and streamline future maintenance.

Apr 1, 2025Concise monthly summary for 2025-04 focusing on key accomplishments for instructure/canvas-lms. Primary delivery this month was a security-hardening feature flag for content exports and migrations, enabling safer and more flexible deployments. The change introduces a feature flag disable_verified_content_export_links to optionally disable JWT-verified links and adjusts download URL generation to omit verifiers when the flag is enabled. This reduces exposure and aligns export behavior with environment-specific security requirements. No major bugs were fixed this month; effort centered on design, implementation, and verification of the flag-driven workflow to improve security and deployment flexibility.
