Leonardo Oliveira Email & Phone Number

I was part of the frontend team for a leading e-commerce platform, using ReactJS, Next.js, NestJS, GraphQL, Jest, and Mockserver. Thanks to Scrum, we were able to work on a collaborative and efficient environment. I contributed to codebase enhancements, delivered high-quality software, and influenced crucial architectural solutions. This experience strengthened my technical skills and teamwork.

I was creating Desvaneio, a social network for readers with over 10000 people, available on Android and iOS, powered by Flutter and Django. The app was developed from the idea to the product and successively improved thanks to user feedback, metrics collection and A/B testing.

I was part of the initial team of four people developing miio, an app essential for anyone who owns an electric vehicle in Portugal. I was responsible for the UI/UX and the implementation. We had a group of beta users to help us constantly improve the experience.

We implemented the app in Flutter.

I collaborated in the development of Dicoogle, a medical image archive. We implemented some web services, both on the backend side, in Java, and on the frontend, in ReactJS.

I developed a cryptographic library in Java for communication with pseudonym-based signatures, supported on bilinear maps. In a second phase, I developed a small Android application to serve as a proof of concept for the library, which was used in encrypted communications with a server.
