Chris Huntingford

Chris Huntingford

I’m a geek and proud to admit it! I’m also a rather large, talkative South African who plays drums, wears horrendous Hawaiian shirts and has an affinity for engaging in as many social gatherings as humanly possible, because, well….I want to experience as much as possible and connect with as many different people as I can! I am, unapologetically, Myself! This zest for interaction and collaboration has led to a fixation on community and an understanding that by bringing people together in the right environment, ANYTHING can be achieved.

I have an intense enthusiasm for technology. I am a terrific tinkerer, a passionate problem solver and a magical maker. As long as I am creating something, I feel fulfilled. Technology provides me with my creative outlet, especially in a digital format. My core focus is on the Microsoft Power Platform, a perfect consolidation of digital technology creating a symphony between both right and left brain hemispheres.

I love to explore the huge mountain of digital building bricks provided by Microsoft to create amazing solutions and solve real problems. I love to bring people together to talk about the amazing things that can be created and can be used to change the way organisations work. I enjoy watching as people, both inexperienced and seasoned, build things and then realise that technology and learning have no boundaries. The sense of digital inclusion within community is what I strive for.

I look forward to connecting with each and every one of you!

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

Most Active Speakers 2022

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 2022.

The 3% is calculated from the pool of all speakers that have at least one accepted session in year 2022. We don't include inactive speakers or speakers that had no accepted sessions during the year. There are around 12 thousand unique accepted speakers this year, the 3% is 371. 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 2022. 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.
