Experience

Online Form Builder | datago

https://www.datago.app/
datago is an online form builder application I developed using Flutter and Firebase. It can be used to create forms to collect data or just simple lists to share, like restaurant QR menus. Around 20 restaurants and cafes are currently using it for their QR menus.

I think this is a perfect example of what Flutter can do: The same codebase is used for Android, iOS, and web apps. The back end is developed in Node.js running on Firebase Cloud Functions, and the database lives on Cloud Firestore.
