Alexey Girin contributed to the epam/ketcher repository over four months, focusing on enhancing test automation, security, and user-facing features. He modernized the test infrastructure using Playwright and TypeScript, refactored autotest suites for maintainability, and introduced new atom interaction methods to streamline execution. Alexey addressed security concerns by validating SGroup types in JavaScript, improving runtime safety and code robustness. He also delivered features such as AxoLabs format support testing and Monomer Creation Wizard enhancements, leveraging React and Vite to improve editing workflows. His work reduced maintenance overhead, stabilized CI pipelines, and accelerated code reviews, demonstrating depth in automation and front-end development.
March 2026 Monthly Summary (epam/ketcher) Key features delivered: - Monomer Creation Wizard enhancements: enabled editing monomer structure, atom properties, and bond types; improved right-click context menus; aligned with updated autotests/spec coverage to ensure reliability of new editing flows. Major bugs fixed and build/test reliability improvements: - Stabilized autotests and developer workflow by fixing Vite server configuration, removing noisy warnings, and refactoring tests to improve reliability. Overall impact and accomplishments: - Enables faster, safer monomer design workflows for users; reduces flaky test runs, shortens feedback loops, and improves developer productivity; lays groundwork for upcoming chemistry editing features. Technologies/skills demonstrated: - React/TypeScript, Vite, Playwright-based autotests, test automation, CI/CD reliability, cross-team collaboration (co-authored commits).

In January 2026, delivered a security-hardening fix for Safe SGroup dispatch in the epam/ketcher repository by validating allowed SGroup types before invoking their handlers, preventing unvalidated dynamic method calls in loadSGroup. This work directly addresses code-scanning alert #22 and improves runtime safety, robustness, and maintainability of the dispatch path. The change was implemented via commit 5c84d09ac2124e29ee861c13e5a063dd1c5af3fd and included refactoring to move constants outside function scope for security and performance reasons, with multiple contributors involved.
