About Alejandro

I am Alejandro Vaca Serrano, an Artificial Intelligence Engineer with 7 years of experience in the sector. My specialty is bringing innovation to productive environments, thus providing a competitive advantage to clients so they are always at the forefront of technology. With a deep understanding of how language models and other modern deep learning architectures work, thanks to projects like RigoBERTa which have allowed me to develop language models in Spanish from scratch.
I have extensive experience in the field of Generative AI. For example, currently in my startup, I have a product, TerapIA, a mental health app with its own Artificial Intelligence, which has been on the market for a year.
