Arjan Rijsdijk

Arjan Rijsdijk

I’m Arjan Rijsdijk, a Power Platform enthusiast, or as I like to call myself, a Power Addict, based in the Rotterdam area in the Netherlands. I work at Powerbouwer on some of the coolest Power Platform projects, always focused on creating real added value for users.

My first introduction to the Power Platform showed me how much impact smart low-code and vibe-code solutions can have. Since then, I’ve kept building, experimenting and learning. What I enjoy most? Working with other Power Platform experts and pushing each other to the next level.

I also love sharing that passion as a speaker. At events and sessions, I talk about the Power Platform, my experiences and the lessons I pick up along the way.

Learn something new every day. Stay Hungry. Stay Foolish.

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

Most Active Speakers 2025

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 2025.

The 3% is calculated from the pool of all speakers that have at least one accepted session in year 2025. We don't include inactive speakers or speakers that had no accepted sessions during the year. There are around 39,000 unique accepted speakers this year, the 3% is 1163. 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 2025. 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.
