Olha Pyvko

Olha Pyvko

Ukrainian living in Sweden, applying engineering mindset for processes creation.
I am always fascinated about solving tricky puzzles and coming up with new ways to look for the problem.
I got a master degree in Telecommunications in 2016 and started my career in IT as a data conversion specialist, working with databases and customers. I got experience from working as a customer support manager, tech writer for user guides and manuals and then as a product specialist, before coming to work close with Agile as a Product Owner. I enjoyed building the right thing as much as building the thing right and fast. My Scrum Master journey started in 2020 and grew from 2 co-located teams to 8 distributed teams working on the same product with LeSS. And it's just the beginning!

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.
