Experience

Rest Countries

https://rest-countries-bnrosa.netlify.app/
I delivered the front-end for the Mentor's REST Countries challenge with a dark theme switcher. It displays data from an API, searches for data, and filters it. Additionally, it routs and allows the user to navigate between related data.

Build.io

https://build.io
Developed a user-friendly deployment platform, offering automated application building and deployment. Similar to Heroku but with enhanced value, the platform seamlessly deploys applications to AWS. It connects to existing Heroku apps and GitHub repositories without any server configuration needed from the end user.

Hitch

https://usehitch.com
Developed an onboarding experience for users to get a quote for a financial service and make their application to qualify for the service. The main challenge was integrating with several APIs, including some legacy ones, to give the users a seamless experience of digitally applying for a service that is still mostly done offline and manually.
