Alexander Lex
Worked on the revisit-studies/study repository, delivering a range of user-facing features and technical improvements over four months. Developed and enhanced interactive demos, including onboarding flows, click-accuracy testing, and survey UX, while restructuring demo content for clarity and maintainability. Addressed data visualization reliability by refining D3.js bar chart color scales to accurately represent datasets with negative and positive values. Improved documentation and configuration management, streamlining onboarding and reducing user friction. Utilized JavaScript, TypeScript, and React to implement robust UI components, introduced Playwright testing for reliability, and maintained project documentation to support both end users and internal development workflows.
