Over a two-month period, contributed to the epam/ketcher repository by developing three features focused on molecular modeling and front end enhancements. Work included implementing stereo-bond support for amino acids and ligands, updating layout and rendering logic to ensure accurate PNG and SVG outputs, and expanding automated test coverage for core features such as structure editing, AxoLabs alignment, and macromolecule layout. Leveraged JavaScript and TypeScript to strengthen UI and automation testing, introducing fixtures and refining test infrastructure to improve reliability and CI feedback. Emphasis was placed on robust validation, error handling, and maintaining high product quality through comprehensive test-driven development.

Feb 1, 2026February 2026 focused on expanding feature support, strengthening test coverage, and improving rendering fidelity for epam/ketcher. Key deliverables include stereo-bond support for AA-LGA with layout and rendering updates, along with validation across PNG and SVG formats. The month also expanded automated tests for core features (structure editing, AxoLabs alignment, library search with HELM/AxoLabs aliases, macromolecule layout, and nucleotide presets), significantly reducing regression risk. Major fixes and stability improvements were driven by test-driven refinements in the AxoLabs format (sense/antisense alignment) and enabling flipping of expanded monomers, which improved test reliability and coverage across the codebase.

Jan 1, 2026January 2026 (2026-01) monthly summary for epam/ketcher focused on strengthening automated testing around monomer handling and sequence mode to boost product quality and CI feedback speed. Key work delivered a Sequence Mode test fixture at the start of test suites, expanded automated coverage for monomer handling, context menus, selection tools, and monomer properties, and enhanced UI test robustness and error handling to prevent regressions. Committed improvements centered on test reliability and clarity, with explicit fixes to failing tests and test infrastructure.
