Around April 2021, Olivier started a new position as BI Teamlead in another Retail Company to support business growth. Besides the challenge to help the BI Team grow and deliver projects on time, he started to use SSAS & Power BI.

In April 2025, Olivier stepped away from internal positions and became an independent consultant.

Hi, I’m Michiel Hamers — a Principal Cloud Expert, Implementation Manager, Trainer, and former Microsoft MVP with over 25 years of experience in the Microsoft ecosystem.

Since 2000, I’ve been helping organizations successfully adopt and optimize Microsoft technologies, with a focus on Azure, cloud architecture, performance, and cost management.

My mission is clear: help people and organizations get the most out of the cloud — with control, clarity, and confidence. Whether coaching colleagues, giving workshops, or advising on cloud-native modernization, I combine deep technical knowledge with a pragmatic, people-focused approach.

When I’m not working, I enjoy life with Sandra — cooking, traveling, and spending time with family and friends. For me, technology is about empowering people, not just systems.

Let’s connect and build something great together.

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.
