PROFILE
Joep Joosten
Worked on the Effect-TS/effect and Effect-TS/effect-smol repositories, delivering three CLI features over two months focused on enhancing usability and accessibility. Developed a CLI multi-select prompt in TypeScript, enabling users to select multiple options with select-all, none, and invert capabilities, complete with UI rendering and input validation. Further improvements included underlining active option labels for better accessibility and introducing dynamic fallback prompts that adapt to runtime conditions. Emphasized robust testing and clear commit traceability throughout. Leveraged skills in CLI development, prompt engineering, and functional programming to create adaptable, user-friendly command-line interfaces without reported bugs during this period.
