As a Frontend Engineer, I was responsible for developing the company's new Checkout solution using web and mobile SDKs and libraries. The SDKs for the web were built with JavaScript, while the mobile ones were developed natively in Kotlin and Swift. Built with Phoenix LiveView, I had the opportunity to deepen my knowledge of SSR (Server Side Rendering) and the development of native mobile and web SDKs and libraries.Checkout solutions are always critical for B2C systems, and this was no different at Ingresse, which sells a considerable number of tickets daily. I was responsible for implementing the UI of the new Checkout, as well as its integration into different mobile platforms of the company.Since its launch, the solution has provided a more fluid purchasing experience, with a simple and streamlined interface that makes life easier for users.

As a React Native developer, I worked on a project for an international client. We merged two codes into a more optimized application, with improved quality and scalability. I provide guidance to the team on testing and coding standards, and assist the Lead Developer in code reviews. We successfully delivered the enhanced application that meets the client's expectations and enhances the user experience in multiple countries. Currently, I am working on developing new features to further improve the application's functionality and performance.

As an intern at dti digital, I worked with one of their biggest clients in Latin America, a leading car rental company. My primary focus was on improving their internal communication software using technologies such as React, Flutter, and .NET Core. One of my biggest accomplishments was implementing a queue for a critical endpoint in their APIs using RabbitMQ, which greatly reduced the time it took to send broadcast notifications to employees. This implementation resulted in a significant reduction in the time it took to send notifications from several minutes to just a few seconds.

As the sole React Native developer, I led the complete redevelopment of a popular education app with over 10,000 users. Our team initially attempted to refactor the existing codebase, but the lack of documentation and best practices prompted us to start from scratch. The end result was a highly maintainable codebase, with an onboarding process for new developers that went from over a month down to just a few days.
