PROFILE
Tamas Kozmer
Worked on the instructure/canvas-android repository, delivering features and fixes that improved release reliability, user experience, and code maintainability. Built file upload flows within LTI WebViews, integrating Android permissions and robust activity result handling using Kotlin and Java. Enhanced release engineering by introducing annotation-based test exclusion and refining versioning practices with Gradle. Addressed UI stability and lifecycle issues, reducing crash risk and improving feedback for users. Standardized code hygiene by enforcing import order and reducing merge conflicts. Focused on end-to-end testing with Espresso, strengthening CI/CD confidence and ensuring critical scenarios were covered in release builds for ongoing quality.

Mar 1, 2026March 2026: Delivered a release process enhancement for instructure/canvas-android by introducing the @ReleaseExclude annotation to skip flaky end-to-end tests in the release pipeline. This reduces false failures, stabilizes releases, and accelerates delivery without changing test code logic. The change is captured in commit 723fa7d677e9ff3a1b8d087bcff0d2461306d7c8 and lays the groundwork for a scalable, annotation-based test-exclusion strategy across the repository.
