Priit worked on the TEHIK-EE/tedi-design-system repository, focusing on enhancing the Select component by introducing a cacheOptions prop. This addition, implemented in TypeScript and JavaScript, allowed developers to control option data caching, defaulting to true for improved performance. By making caching behavior explicit through a prop-based API, Priit reduced redundant data fetching and aligned caching logic across downstream applications. The work demonstrated skills in front-end development, React component design, and performance optimization. The update addressed previous inconsistencies in caching, resulting in faster option rendering, reduced network traffic, and a more predictable user experience for applications using the design system.
