También me gusta trastear con inteligencia artificial, Python, SQL, Machine Learning y PySpark, porque al final, ¿quién puede resistirse a un buen reto técnico?

Cuando no estoy entre datos, modelos y reuniones proponiendo ideas locas, me encontrarás planificando el próximo viaje, con un plato bien picante delante o haciendo fotos como una obsesa. Ah, y contando chistes malos, porque alguien tiene que romper el hielo, ¿no?

Compartir conocimientos y conectar con comunidades de datos es lo que realmente me llena. Los datos y la tecnología no solo nos hacen trabajar mejor, también pueden cambiar cómo vivimos y entendemos el mundo.

Please note that Sessionize is not responsible for the accuracy or validity of the data provided by speakers.

Most Active Speakers 2025

Every year, we put together a list of the most active speakers. This list features the top 3% of speakers who have participated in events using Sessionize during the 2025.

The 3% is calculated from the pool of all speakers that have at least one accepted session in year 2025. We don't include inactive speakers or speakers that had no accepted sessions during the year. There are around 39,000 unique accepted speakers this year, the 3% is 1163. Not all of them have their speaker profiles set as public, and we respect that, so the list doesn't show all of them.

The calculation is based on the number of accepted events, that's the main criteria, but to get more refined results we also look at things like multiple sessions per event, sharing a session with a co-speaker and how big the event is. Number of submissions and declined sessions don't affect the list.

Please note that the count of events and sessions in this list does not represent the number of events and sessions from the year 2025. Instead, it shows the number of events and sessions featured on the speaker's public speaker profile; these numbers have nothing to do with the award itself.
