Contributed to the epam/ketcher repository by building and refining features for chemical structure drawing and macromolecule sequence editing, with a focus on improving scientific workflows and UI reliability. Leveraged React, TypeScript, and JavaScript to implement antisense strand generation, enhance sequence editor usability, and expand the 3D template library. Addressed user experience issues by fixing selection sensitivity, stabilizing UI tests, and correcting visual rendering of monomer aliases. Integrated new hooks and updated event handling to ensure robust editor interactions. These efforts reduced manual steps for scientists, improved data interpretation, and strengthened the accuracy and accessibility of molecular editing tools.

Sep 1, 2025September 2025 monthly summary for epam/ketcher. Delivered two critical bug fixes enhancing UI reliability and visual accuracy in molecule editing. Implemented a useCreateMonomer hook and integrated into the SelectionMenuItems to reveal the 'Create a monomer' option in the right-click context menu under relevant conditions, with tests updated to improve canvas stability. Fixed IDT alias display for CHEM 5TAMRA by refining useIDTAliasesTextForMonomer to render aliases correctly, improving structural visuals. These efforts improved workflow consistency, reduced mis-edits, and strengthened rendering fidelity across the editor.
