Experience
Middleway
A platform that allows the creation of multiprotocol IoT networks and the management of smart objects with advanced analytics. I initially joined as a front-end developer, working with JavaScript and React. After three months, I took over as a full-stack developer and refactored the front end to TypeScript. On the back end we used Python with GraphQL and Apache Cassandra for the database. Additionally, I supervised a junior back-end developer.
Gestão Otimizada
An ERP used to manage the partner networks. I started as a front-end developer at the beginning of the project and designed the screens and the system's usability. I also assisted in the construction of the endpoint contracts. After one year, it was necessary to refactor the front end into TypeScript and the database, from MongoDB to PostgreSQL. I took over as software architect and we hired four interns. From then on, my responsibilities were to architect the microservices, create the database modeling, provide mentoring to the new developers, and create the necessary CI/CD automation.
Bees Link
https://bees.com/An eCommerce made for a large supermarket chains in Brazil to buy products from Ab inBev. This project was a refactoring of a very critical application in the company with an annual cash flow of over one billion dollars. The original application was built in Magento and the project involved a back end built in .NET and the front end in React with TypeScript. I was sole front-end developer and built the initial front-end architecture and the first major functionalities of the system. I chose RecoilJS for the state management of the application and even though it was in the experimental version, it matched very well with the system requirements. As the eCommerce evolved, the global section of the company became interested in the project and exported it as a part of the Bees global application for the rest of the world.
