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".

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.
