Sergei Mikhailov contributed to the oat-sa/tao-community and oat-sa/extension-tao-testqti repositories by building and maintaining features that improved assessment reliability and user experience. He extended audio recording durations, upgraded core dependencies, and enhanced timeout handling to support empty responses, addressing real-world assessment needs. Using PHP, Composer, and PHPUnit, Sergei managed configuration and dependency updates to ensure stable deployments and consistent behavior across environments. His work included targeted bug fixes, such as resolving service initialization issues and preventing session errors, demonstrating a thoughtful approach to backend and frontend development. The solutions delivered were robust, maintainable, and production-focused.

In September 2025, delivered reliability and maintenance improvements for the oat-sa/extension-tao-testqti extension. Key changes include robust timeout handling to permit empty responses and an upstream dependency upgrade to tao-test-runner-qti-fe v4.3.3. These updates reduce session-errors in timed assessments, improve user experience, and align the project with the latest upstream fixes, supporting smoother production runs and lower support overhead.
