PROFILE
Igor Kostrubin
Over three months, Kostrubin enhanced the epam/ketcher repository by focusing on stability and user experience in macromolecule editing workflows. He addressed critical bugs in Indigo function processing, improving JSON deserialization logic and refining UI behaviors to prevent crashes and reduce user confusion. Using TypeScript, JavaScript, and React, he synchronized library tabs with sequence mode, refactored file comparison logic, and expanded automated test coverage for multiple macromolecule types. His work also included optimizing canvas layout logic to prevent unnecessary re-layouts, thereby increasing editing accuracy. These targeted improvements reduced runtime errors and support overhead, demonstrating thoughtful, issue-driven engineering depth.

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.
