PROFILE
Maksim Labovič
Maksim Labovich contributed to the epam/ketcher repository by developing and refining features that enhance macromolecule editing and visualization. Over five months, he delivered a robust SVG export capability with flexible margin handling, unified bond length constants for consistent rendering, and improved the reliability of polymer bond creation. Maksim addressed critical bugs such as orphan atom removal after bond deletions and corrected sequence number rendering in the Macromolecule Editor. His work involved extensive code refactoring, debugging, and automated testing, leveraging JavaScript, TypeScript, and React to improve maintainability, data accuracy, and user experience in complex chemical structure editing workflows.

Sep 1, 2025September 2025 monthly summary for epam/ketcher: Delivered a robust SVG saving enhancement with precise margin offset handling. The feature introduces offset calculations when saving SVG files, refactors getSvgFromDrawnStructures to support flexible margin inputs (numeric and object-based), and updates the Save modal to correctly calculate and apply offsets. This work improves export accuracy, saves time for users, and increases flexibility for margins.

Aug 1, 2025Concise monthly summary for 2025-08 focusing on epam/ketcher. Key bug fix: macromolecule editor now removes atoms that become orphan after deleting bonds by refactoring the bond deletion logic to ensure proper cleanup and maintain structure integrity. This reduces data corruption risk and improves editing workflow for macromolecules, as well as downstream rendering/export.

Feb 1, 2025February 2025: Focused on reinforcing the robustness of polymer bond creation in the Ketcher editor for epam/ketcher. Implemented attachment-point enforcement, removed redundant test helpers, and resolved a critical bonding bug that allowed unlimited monomer-to-microstructure bonds. This work enhances reliability of macromolecule structure generation, improves user experience, and strengthens code quality and maintainability.

Dec 1, 2024December 2024: Fixed a rendering inconsistency for monomer bonds when loading from HELM vs library. Unified the bond length constant by renaming/reusing RNA_MONOMER_DISTANCE as CELL_WIDTH across the codebase to ensure consistent representation and rendering irrespective of loading source. No new features were released this month; the focus was stability and correctness of visualization, supported by a specific fix for issue #6026/#6152. Result: consistent geometry across loading sources, reduced visual defects, and improved maintainability of the codebase. Technologies/skills demonstrated include cross-module refactor, constant-driven geometry handling, and regression testing.
