Simon Painter

Simon Painter

I've been working as a .NET developer for over 16 years now in a variety of industries including government, retail and manufacturing. But I've been hacking around with computer code since I was old enough to read my Dad's copy of the ZX Spectrum BASIC coders manual.

I've been speaking about Functional C# at various user groups and conferences around the UK, USA, Europe and Australia and am particularly interested in seeing just how far we can push C# without breaking it.

In 2023 I released my first technical book: "Functional Programming with C#", published by O'Reilly Media.

When I'm not coding, or running after my two small children, I have been known to enjoy the classic series of Doctor Who, Fighting Fantasy Gamebooks, Cryptic Crosswords, and rather more coffee than is probably good for me.

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.
