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.


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.
