05. About me

Antonio Toro Jaén

Since I was a child, I have had a great passion for computer science. When the time came to decide what to study, I did not hesitate, I trained as a developer. After a year of work experience, I confirmed that I was on the right path, I decided to take a step further to become an engineer. Today I combine my work as a developer with a Master's Degree in Artificial Intelligence, the field where I want to focus my career.
