Bretislav worked on enhancing charting and documentation capabilities across the vaadin/flow-components and vaadin/docs repositories, focusing on Gantt chart features and developer onboarding. He implemented interactive Gantt chart support with drag-and-drop and modernized time handling using Java and TypeScript, enabling more flexible project planning interfaces. In vaadin/docs, Bretislav authored comprehensive guides for new features, including detailed documentation for Gantt charts and grid pagination, with cross-library examples in React and Flow. He also introduced usage analytics to track feature adoption and improved documentation discoverability through strategic cross-references, demonstrating depth in both technical implementation and user-focused documentation practices.

In May 2025, delivered a focused documentation enhancement for Grid Pagination in vaadin/docs, including a new Grid Pagination chapter with cross-library examples (Lit, Flow, React) that demonstrate manual pagination and contrast with infinite scrolling. This work improves developer onboarding, reduces integration guesswork, and supports faster adoption of grid pagination patterns.
