Fredy contributed to the jumper-exchange/jumper-exchange repository by enhancing the Earn page’s wallet connect flow, focusing on both reliability and user experience. He refactored front end tests using TypeScript and JavaScript, replacing global waits with targeted checks for chains, bridges, and DEXs, which reduced test flakiness and accelerated CI feedback. Fredy also improved the wallet connection process by ensuring the connect button remained visible and enabled after page load, and streamlined the wallet selection dialog. These changes strengthened onboarding and made automated releases more predictable, demonstrating thoughtful application of front end development and testing skills within a short project period.
