Full stack developer, Lead architect - GoCup - Children’s soccer tournament management system

Full Stack Developer and Lead Architect for a platform that manages the whole infrastructure of soccer tournaments, from the athletes' subscription to resolving the teams' classification. This is an e-commerce platform built with Ruby on Rails and React for the biggest children’s soccer tournament in Latin America. This site has customers from all over the world and offers support for multiple payment platforms. It offers hosting and subscription packages for the tournament and thousands of clients every year. ​The first production version of the platform was released in a challenging deadline of 4 months due to the tournament's official date in 2016. The first release was a success and the platform is upgraded every year. Since 2016 the platform receives a pack of new features every year due to the growth of the tournament's infrastructure. The website has 10 administrators, but over 10k viewers during the 2 weeks long event, since the system supplies data for the official mobile app. I was responsible for the system’s architecture, planning the sprints, defining the scope of the releases, leading the daily follow-up with the team and the clients.

Full Stack Developer - GS1 Source
Full Stack Developer - GS1 Source

GS1 is the company that maintains the barcodes of products worldwide. This site offers subscription plans for customers who wish to consume the GS1 APIs. Each plan offers the customer a number of requests per month for a fixed monthly cost. When the customer exceeds the max number of requests, an extra fee is charged for every additional request. The platform tracks the number of requests made by the customers, controls their access to APIs based on the subscribed plan, shows usage statistics and also generates invoices. I’ve worked as the full stack developer of this project along with the company’s .NET architect, also using React stack for the first time. The platform had some upgrades to the catalog of available APIs.
