BrenoGO | Moco
Moco is a web application to control personal finances. Users can manage their expenses, incomes, receipts, and bills to pay. The app is still in development, but I have already used it since 2019 to control my finances, and it has been very helpful.

Barcode Scanner

Developed a mobile app that reads barcodes and stores the list of codes. The users send the list to a file in AWS S3 Bucket through the AWS Lambda function. Many users can use the app simultaneously, and Lambda will concatenate all the users' lists in this single file. It simplifies the stock conference.
