PROFILE
Alexey Girin
Worked on the epam/ketcher repository over four months, delivering features and fixes focused on test automation, security, and front end enhancements. Modernized the test infrastructure using Playwright and TypeScript, refactored autotests for maintainability, and introduced new atom interaction methods to streamline execution. Addressed security by validating SGroup dispatch paths in JavaScript, improving runtime safety and maintainability. Enhanced the Monomer Creation Wizard with structure editing and improved context menus, while stabilizing the developer workflow by fixing Vite server configuration and reducing test flakiness. Contributed to configuration management and CI/CD reliability, demonstrating strengths in automation, React, and full stack development.

Jan 1, 2026In 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.
