Marco De Sanctis

Marco De Sanctis

My name is Marco and I have an incredible passion for technology which I had the privilege to turn into a job. I’ve been working with .NET since the first beta, focusing on ASP.NET and, more generally, anything that is web related. I’ve been an early adopter of Microsoft Azure – who remembers the portal in Silverlight? :) – and, since its introduction, Cloud technologies have represented the core of my professional interest.

Today I work in the beautiful London, where I’m playing my part in saving the planet being the CTO at Mondra. Getting involved in the .NET and Azure community is also a key aspect of my profession: I’m convinced that knowledge sharing is one of the best ways to improve our professional skills, and therefore I try to dedicate as much time as I can to activities such as writing articles or speaking at conferences and meetups. Thanks to that, I’ve been awarded as a Microsoft MVP for the last 15 years in a row.

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

Most Active Speakers 2023

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 2023.

The 3% is calculated from the pool of all speakers that have at least one accepted session in year 2023. We don't include inactive speakers or speakers that had no accepted sessions during the year. There are around 25 thousand unique accepted speakers this year, the 3% is 771. 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 2023. 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.
