PROFILE
Igor Kostrubin
Worked on the epam/ketcher repository over three months, focusing on enhancing macromolecule editing workflows and improving application stability. Addressed critical issues in Indigo function processing by refining JSON deserialization logic and implementing UI/UX improvements to streamline editing and reduce runtime errors. Delivered a feature that synchronized the library tab with the typing type switcher, refactored file comparison logic, and expanded automated test coverage for multiple macromolecule types. Utilized JavaScript, TypeScript, and automated testing to resolve layout glitches, prevent unnecessary canvas re-layouts, and ensure reliable operation. The work emphasized robust debugging, regression testing, and collaborative integration for long-term maintainability.

Dec 1, 2024December 2024: Focused on stabilizing Indigo function processing and improving editing UX in epam/ketcher. Delivered a critical bug fix for Indigo Functions JSON deserialization when a monomer is present on the micro canvas, preventing crashes and enabling reliable operation of Indigo functions. Implemented UI/UX improvements to prevent unnecessary dropdowns and to auto-scroll the canvas during text editing, improving visibility of newly added sequences. These changes reduce runtime error surface, enhance user productivity, and demonstrate proficiency in TypeScript/React UI, JSON handling, and issue-driven debugging. Business value includes higher reliability for automated workflows, smoother authoring experience, reduced support overhead, and faster feature delivery.
