Stefan contributed to dvsa/vol-functional-tests by engineering a robust functional testing framework that improved deployment reliability and test automation. He implemented batch processing workflows, modernized UI automation with XPath selectors and wait synchronization, and integrated AWS Batch for scalable test execution. Using Java and Selenium, Stefan addressed flakiness in end-to-end tests by refining wait logic, enhancing error handling, and automating page refreshes. He maintained CI/CD pipelines with GitHub Actions, aligning versioning and dependencies to reduce drift. His work restored test coverage, stabilized sign-in flows, and enabled faster, safer releases, demonstrating depth in backend development, configuration management, and workflow automation.

July 2025 performance: Across dvsa/vol-functional-tests and dvsa/vol-app, delivered reliability, security, and deployment-readiness improvements with measurable business impact. Key outcomes include stabilized sign-in flow and sign-in page reliability, improved ActiveSupport compatibility and library version alignment, and proactive dependency maintenance. UI stability enhancements reduced flaky UI tests by addressing scroll/wait behavior. A new Internal Production User feature was implemented in vol-functional-tests, and vol-app now uses automated CD metadata updates with a prerelease tag 5.20.0-rc1, accelerating controlled releases. The combined work reduces support tickets related to authentication, lowers risk from dependency drift, and shortens time-to-market for releases.

June 2025 highlights: Significant improvements to functional testing and deployment readiness across two repos. In dvsa/vol-functional-tests, we hardened CI/infrastructure and test utilities (lower Selenium session timeout; ActiveSupport updates; refreshed mailpit/CI workflow), delivering more reliable test runs and faster feedback. We stabilized UI/test flows with extended waits, fixes to sign-in, and improved search/checkbox interactions; flaky behavior was reduced via stale-element retries and streamlined UI steps (including removing an unnecessary click) and by increasing operation timeouts to reduce timeouts and flakes. Maintenance work around Active Support updates and test cleanup further increased reliability. In dvsa/vol-app, deployment pipeline reliability was enhanced by aligning CD trigger timestamps through comprehensive .gitignore updates to reflect current CD timing, ensuring pipelines trigger consistently. Overall impact: fewer flaky tests, faster release cycles, more predictable reporting, and stronger user-facing flows. Technologies/skills demonstrated: Ruby/Rails dependencies (ActiveSupport), Selenium/WebDriver based test automation, CI/CD workflow optimization, mailpit integration, and disciplined Git hygiene.
