PROFILE
Artem Zhmurov
Over 16 months, Dmitry Zhmurov engineered core backend and developer tooling for the manytask/manytask repository, focusing on scalable course management and robust authentication. He designed and implemented modular APIs, abstracted repository management, and migrated data storage from Google Sheets to a database-backed architecture using Python and SQLAlchemy. Dmitry introduced CI/CD automation, improved configuration via environment variables, and enhanced testability with mock interfaces. His work included refining authentication flows with OAuth, strengthening admin controls, and modernizing build and deployment processes. Through detailed documentation and code refactoring, he improved maintainability, onboarding, and reliability, demonstrating depth in backend development and system design.

Apr 1, 2026April 2026 focused on delivering robust documentation and tooling for Checker, stabilizing release notes workflows, and improving code health across manytask/manytask. Key outcomes include a consolidated Checker integration with comprehensive docs and CI validation, a decoupled Release Drafter with commit-message-based categorization, and cleanup of deprecated methods to simplify the API surface. Also fixed API/Checker plugin issues and adjusted test reporting to emphasize pass/fail results, improving reliability and business-facing visibility.

Mar 1, 2026March 2026 (2026-03) focused on enhancing configurability and CI tooling for manytask/manytask. Delivered two major features: Configurable Plugin Options (executable paths for clang-format/clang-tidy and a build directory argument for the forbidden checker plugin) and Checker Integration: Testing, Linting, and Cleanup (integration into test and lint workflows with cleanup of outdated files after the integration). Updated Makefile to run all checks on both Manytask and Checker, and ensured the checker file is included in linting/testing. This work reduces configuration friction, strengthens static analysis, and improves CI reliability. Technologies used included clang-format/clang-tidy tooling, build-folder management, Makefile-driven CI tasks, and codebase hygiene.
