PROFILE
Mariam-khutuashvili
Mariam Khutuashvili contributed to the epam/ketcher repository by leading a TypeScript migration of core UI components, focusing on improving type safety, maintainability, and code quality. She refactored JavaScript components such as Tabs, SystemFonts, and BondTool, introducing explicit type definitions and interfaces to reduce runtime errors and enable safer refactoring. Using React and Redux, Mariam enhanced bond rendering logic for aromatic and hydrogen bonds, streamlined mouse interaction handling, and improved the user experience in sync edit mode. She also added unit tests for serialization and rendering, strengthening the codebase and supporting faster, more reliable delivery of future features.

Apr 1, 2026April 2026 (2026-04) monthly summary for epam/ketcher. Key features delivered this period focus on type-safety and maintainability improvements through a targeted TypeScript migration of core UI components. Specifically, LabelEdit, Refrag, and SGroup were converted to TypeScript with explicit prop/type definitions, accompanied by tests for serialization/deserialization and DAT type rendering. Major bugs fixed: none recorded in this period. Overall impact: strengthens the codebase with stronger typing, safer refactors, and improved maintainability, enabling faster delivery of future UI features and reduced runtime type errors. Technologies and skills demonstrated: TypeScript migration, React component typing, test coverage for serialization and rendering, and emphasis on code quality and maintainability.

Mar 1, 2026March 2026 monthly summary for epam/ketcher focusing on TypeScript migration, UI improvements, and bond/tool rendering enhancements. Delivered a broad TypeScript migration across UI components with added type definitions, interfaces, and type guards; improved code quality via optional chaining and static analysis to reduce warnings and errors. Refactored the BondTool for mousemove handling and drag logic to dramatically reduce cognitive complexity and stabilize bond creation. Improved bond rendering for aromatic and hydrogen bonds and overall layout. Addressed sync edit mode UX by hiding counter numbers >9 when caret is on/near the associated symbol. Migrated multiple JS components to TS (Tabs, SystemFonts, Template-attach, FormulaInput, StructEditor, SDataFieldset) enabling safer refactors and better reuse of types/store state.Overall impact includes reduced risk in future changes, fewer runtime warnings, smoother onboarding for new engineers, and a clearer path for ongoing feature delivery.
