• Participated in the development and maintenance of the diferente products and projects.• Worked with the Project Manager to provide estimates and schedules for technical activites.• Performed code reviews for standards, quality assurance and security audit purposes• Analyzed requirements and produce documentation for architectural recommendations and systems.Technologies: Reactjs, SynfonyPHP

Impacted a market of 30 million people around the world who suffer epilepsy by contributing the predition of an epileptic seizure by Filtering and cleaning an MIT Dataset of EEG signals in order to be set in a neural network• Implemented a Convolutional Neural Network (CNN) to analyze a dataset of EGG signals, this was done to predict epileptic seizures and measure the effectiveness of the neural network. Techonologies used: Tensorflow, Pandas, Pythorch.

* Improved the communication between the team development and the client. * Improved the organization of the team by leading the daily meetings and prioritizing the tasks of our daily work.* Train the next team member who took the role of Product Owner
