Alessandro Melchiori

Software craftsman, husband, father, ex-sportsman and inquiring reader. Since I was young I have loved taking apart and reassembling things to understand how they work. Now, this passion has become my job: the step from Lego® to software development was small.
Finding the best possible solution so that a complex system can work at its best and making it run smoothly are the goals of my work. C# and Azure make up my survival toolkit and help me cruise through distributed systems and enterprise solutions, with ease.
Be it a command or an event, I try to do my best in contributing to the life of the communities that have adopted me, trying to “give back” at least a part of what I have received over these years.

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.
