A music-practice app to help piano players improve 4x faster, thanks to a music theory gym and guided practice sessions. Everything is data-driven, customizable, and follows the official music academy system in Spain.

A Flutter app that connects athletes worldwide based on the sports they do and their geolocation. I developed the entire app and its servers and managed every technology-related topic. I led a team of content creators and one community manager in launching the MVP within three months. After one year, we have more than 15.000 users, and Sports Buddy is now one of the leading sports apps in Spain.

Honors in my final degree project.

This article aims to analyze what adversarial attacks on neural networks are and whether networks can take advantage of these attacks to obtain more training data, increasing their prediction accuracy and robustness to future attacks. We will also find if one input generated by an attack on one network works on other similar networks.
More than 30 adversarial attacks have been generated and will be tested against three different network architectures. One of the networks will be re-trained with these attacks and finally tested to see if these attacks work as data augmentation and if the network sturdiness increases.
We will see that one attack generated on network A does not work on some other network B. This attack confuses network B, and the prediction obtained is random but not determined. We will also see that adversarial attacks can be used as data augmentation strategies and that the same kind of attacks do not fool the networks after a re-train step. The last experiment will show us that there is no significant time increase in executing the attacks on a re-trained network C.

A Flutter-based app to make micro-donations to NGOs.

I developed everything (front/back). As the CEO, I organized all the projects and led three team members based in Barcelona and Madrid and non-technical tasks.
