Experience
Candidus
Candidus is an IoT device added to greenhouses in order to work as a central to automate crop growth. It uses sensors to gather information from the environment. It has its own algorithm that decides when to turn ON/OFF lights based on the light provided, the kind of crop being cultivated, and the grower's objective (grow, flourish, etc.).
Olivia AI
A personal finance native app built for both Android and iOS, with back end in Node.js. I participated in developing features and in all steps of the project, using Android Native in Kotlin, iOS Native in Swift 3, back-end microservices and REST APIs in Node.js.
Test Automation Platform for Mobile Apps
A Ruby-based test automation platform to perform black-box testing in already compiled mobile apps for Android and iOS.
The apps were both Native written in Java, Kotlin, Objective-C, Swift, or Unity-based. The test platform used Appium and Selenium WebDriver to create human-readable layers of test tools used by test automators. The platform also generates test reports in several formats such as HTML, pdf, JSON, and XML with screenshots to understand test issues better.
In addition, the platform also includes backdoor libs, C# for Unity, Java for Android and Swift for iOS that could be installed in a development version of the app being tested. These backdoors enable a class to be implemented in the app with public methods and open a door in the device being tested so these open methods could be accessed from external consumers in the same network.

Gemain
I developed the front end for the website using jQuery, the client's portal with AngularJS, and the back end as a REST API with C#. Even though the company does not exist anymore, a preview of the website is still running.
