Worked on refining the Macromolecules Save dialog UI in the epam/ketcher repository, focusing on improving visual consistency and user experience. Addressed layout issues by aligning the height of the File format dropdown with the File name input, removing hardcoded height constraints, and utilizing Flexbox with alignItems set to flex-end for better component alignment. Collaborated with another developer to ensure the changes matched the design system, resulting in a more intuitive and maintainable save-flow interface. The work leveraged React for component structure, along with CSS and TypeScript to implement flexible sizing and enhance the overall front end design.
