Experience
Minha Estácio App
https://play.google.com/store/apps/details?id=br.estacio.estaciomobile&hl=pt_BR&gl=USMinha Estácio is the name of a white-label mobile app built in React Native, which connects with a back end built in Node.js.
I was in charge of the evolution of this legacy learning platform using React Native. I made design decisions that complied with the business team while making, supporting, or delegating the technical refinements to the developers' team.
We completely re-designed the back end following clean architecture principles, supported by robust testing and a solid DevOps culture using Jest, SuperTest, and Azure DevOps.
We've also created a coexistence architecture with folder by feature structure for the mobile app, allowing us to separate the old things developed with bad practices from the new features designed with great responsibility and high testing coverage. We used a React Native Testing Library, Appium, Effector, and Redux.
From the DevOps point of view, we started with a hard-to-build delivery app to have an automated pipeline that runs tests, generates reports, and publishes the app on both iOS and Android environments without manual intervention.

Virtual Classroom
I have created a white label web app for a large education company in Brazil using React, which enabled them to deliver the same app to several brands in the company. The app is considered a very strategic product in its portfolio as it ensures a great learning experience for its students.
Technically, we have followed a theme strategy by using styled-components and creating React libraries and a test pyramid approach, implemented with Jest, React Testing Libray, and Cypress to ensure the quality aspects.
We have used Azure DevOps Pipelines to deliver our app as it handles all quality stages, such as lint, tests, and reports, and delivers to an S3 bucket accessible by a CloudFront route.

Estácio Renova
https://www.youtube.com/watch?v=v8qFUFOKogkRenova is a new experience for students' enrollment renewal. It is a responsive, user-friendly, and mobile-first experience that has replaced the older one, which was pretty complicated to use, causing misunderstanding and a high abandonment level from the students, affecting one of its primary revenue sources.
Technically, the stack was composed of microservices RESTful connecting in PostgreSQL and DynamoDB databases. A WebApp written in React using hooks, Context API, and other modern features. We've used Cognito and Lambda Functions connected to the API Gateway for authentication.
