Experience

Itago | Disposable Chats

This progressive web application allows users to create disposable chat rooms without registration. Users do not require email or social media accounts to start using this application and creating private rooms. They are also allowed to create links to send to other people in order to join the chatroom. Itago gives the users the possibility to delete all their messages and destroy all chatrooms that they have created. I built the front and back ends for this full-stack project and deployed it in AWS.

OpinionFeeds

http://opinionfeeds.com
OpinionFeeds is a web application that allows companies to create portals for their team and clients so they can receive feedback anonymously.

I built this personal project as a solo developer working on product, UI/UX designing, front end, back end, and deployment.
