Vjekoslav Babic

Vjekoslav Babic

Vjekoslav Babić (Vjeko) is a Business Central architect, developer, trainer, author and blogger with over three decades of IT experience, two of which have been spent in the Business Central ecosystem.

His passion lies in web and mobile technologies, but deep down he's an incurable hacker who loves writing code and breaking things apart to see how they work.

As a frequent conference speaker and blogger, Vjeko pushes the boundaries of what's possible, connecting Business Central with anything that can be plugged into it through obscure loopholes or undocumented interfaces, especially when they're not meant to be used that way. In his view, nothing is really meant for any particular purpose, and figuring out how to make things useful beyond their intended design is the meaning of life.

Since 2010, Vjeko has been awarded the Microsoft Dynamics NAV MVP. You can find him at his blog "Vjeko.com - ideas in the cloud".

Florian Salzmann

I help organizations strengthen security, automate processes, and streamline device management across Intune, Windows 365, and the Microsoft Security stack. My work focuses on closing real gaps, from PowerShell-driven Intune automation and third-party patching to hands-on Security Copilot implementations.

On Stage
I'm a regular speaker at leading IT and security conferences, including MEM Summit Paris (which I co-organize), NIC Summit Oslo, WP Ninja Summits, and Cloud Technology Town Hall. My sessions are technical, demo-heavy, and built around solutions you can take back to work on Monday.

Beyond the Stage
I write at scloud.work, contribute a weekly short-format column to msnugget.com, and create tech demos and automation guides that go deeper on the topics I cover live. If it involves modern device management, security, or making Intune do things Microsoft hasn't gotten around to yet, I'm probably working on it.

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.
