Rodrigo Liberoff

Rodrigo Liberoff

Hi there… I'm Rodrigo, a Microsoft technologies veteran with more than 20+ years of experience.

In recent years, I have focused on Artificial Intelligence technologies, starting with Natural Language Processing (NPL) services such as Azure AI Language (previously known as Azure Cognitive Service for Language) and now with Generative AI (mainly Azure OpenAI), working on the potential and challenges (technical and ethical) of these new technologies and trying to help the community face them.

I also generate digital content to share my experience working with Artificial Intelligence services and resources, sharing tricks and strategies that anyone can follow, taking knowledge from the most basic levels to the most advanced. I publish my content through my YouTube channel (https://www.youtube.com/@CODERTECTURA), Twitch (https://www.twitch.tv/codertectura), LinkedIn and X social networks (formerly Twitter), my personal blog (www.codertectura.com), and other media such as the ENCAMINA blog (my current company), allowing me to reach more people through these channels.

I am a co-founder and main contributor of the open-source library ENMARCHA (https://github.com/Encamina/enmarcha), which showcases some of my experience and knowledge with Microsoft and Azure libraries for Artificial Intelligence. The idea is to help the community adopt these technologies and accelerate their own projects and initiatives.

If you want, we can connect at @rliberoff 😎

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

Most Active Speakers 2024

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 2024.

The 3% is calculated from the pool of all speakers that have at least one accepted session in year 2024. We don't include inactive speakers or speakers that had no accepted sessions during the year. There are around 38,000 unique accepted speakers this year, the 3% is 1036. 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 2024. 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.
