Over a three-month period, contributed to the epam/ketcher repository by delivering three targeted features that enhanced chemical drawing workflows. Developed a new star atom symbol, integrating it into the rendering and atom logic to expand molecule editing capabilities. Enhanced HELM notation support by updating monomer definitions, adding alias handling, and implementing compatibility checks, all backed by expanded JavaScript-based autotests to ensure data integrity. Improved macromolecule selection in Macromolecule Mode by introducing Lasso and Fragment tools, refactoring selection logic with TypeScript for maintainability, and adding hotkey support. Focused on robust UI/UX development, software design, and comprehensive testing throughout each release.
