Chrystler developed the Video Chapters Navigation feature for the cvat-ai/cvat repository, enhancing the Frame Player to display and navigate between video chapters during annotation. The work involved designing new classes and methods in JavaScript and TypeScript to manage chapter metadata, as well as integrating navigation controls into the React-based user interface. By aligning the new functionality with existing annotation workflows, Chrystler improved annotation speed and consistency for users. The feature was delivered end-to-end within a month, demonstrating depth in both frontend and full stack development. No bug fixes were recorded, as the focus remained on robust feature implementation and integration.
