International Courrier Platform

An eCommerce platform based on VTEX for the sale of beverages. I led the core team, which was in charge of implementing all the internal and third-party integrations.

In the same way, I developed several Lambda functions using Serverless Framework to maintain a structure that would allow us to operate in around ten countries.

Colmapp

An eCommerce application based on the Magento framework. Founding member of the team and participant in all its processes. I initially worked on the back-end of the website, then created the mobile application for sellers, and finally in the native Android and iOS applications for consumers.

As we had more users, I optimized the response times and the number of concurrent users within the mobile applications. Finally, when the team grew, I became the team leader, helping with processing new requirements and the search for best practices.

A news web portal that was created using WordPress and an iOS application made in Swift. This portal was fed from more than three different sources in 3+ different services, and all of them were obtained through a SOAP service.

Rifalia System

Developed the back-end logic and mobile app using Cordova of a web platform for scheduling and performing raffles with different prizes using PHP. I also worked on the front-end using jQuery and HTML, and configured cron jobs for raffle notifications.
