Małgorzata Janeczek

Małgorzata Janeczek

Gosia falls down rabbit holes for a living. Sometimes it's a .NET bug, sometimes it's React state that shouldn't be doing that, sometimes it's a random Wikipedia tangent at 11pm or random switch to Go, because why not - either way, she comes back up with something worth sharing, which is why she ended up on stages and, later, with a blog nobody asked for but people (sometimes) read it anyway.

By day she's a full-stack developer (.NET/React mostly) who's serious about test automation and AI. She started out studying Automatic Control and Robotics, took one look at code, and never looked back.

Off dutyshe is a mom, painter, and piano beginner whose progress can generously be described as “meh” (the piano remains undefeated). She rewatches the same sitcoms and TV Series on a loop, and reads crime fiction like she's building a case file of her own. Ask her about any of it. She has opinions, and probably a tangent ready to go. She is a lifelong learner who genuinely enjoys sharing whatever she just happened to dig into this time.

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.
