Experience

Programming Workshop Course

https://taller-de-programacion-2.github.io/

I created a programming workshop as an ad-honorem teacher assistant, tutoring the students and grading their assignments.

In the course, students learn how to integrate heterogeneous technologies to build a microsystem architecture, including a mobile and web front end. I've been giving the course's React and React Native module lectures.

Flight Ticketing System

A back-end service that integrates with several heterogeneous external providers to create a standardized REST API that internal clients consume to issue flight tickets. I joined the DevOps team as a team leader.

Flight Checkout Orchestration Back-end Service

A flight checkout orchestration back-end service. I joined the team as a software engineer and became the team lead after some years. We formed a DevOps team in charge of several microservices that integrate with internal clients and providers.

Credit Plan for Buying Cars

This project is a system for managing credit plans for buying cars. I joined it as a trainee and eventually became a semi-senior developer, learning a lot from this big project while working with many collaborators.
