Chris Klug

Chris Klug

Chris Klug has been building software professionally since sometime around 2000, back when .NET was new, CSS was a suggestion, and Roy Fielding’s REST paper had just been published. Since then he has written code for everything from model agencies to online sports betting to professional sail racing, because staying in one industry sounded far too boring.

He has been a Microsoft MVP for something like 15 years (depending on when he last updated this abstract), which either means he knows a thing or two or that he just talks a lot. Possibly both, but we all know the latter is a given. These days he works at Active Solution in Stockholm, helping clients solve problems and build better systems.

When he is not writing code, Chris is usually geeking out on some form of extreme sport like skydiving, kitesurfing, snowboarding, mountain biking, or wing foiling. He loves learning new things and spends way too much time thinking about weird stuff most people never even notice.

Pradeep Sharma

Pradeep Sharma

Pradeep is as old as the internet but he didn’t have reliable access to the electricity or the internet until he entered IIT Roorkee where he studied electronics and programming. His interest in programming grew more after his work as a Computer Science Researcher at L3S Research Center (Germany) and Sabanci University (Istanbul). His newfound passion and early successes propelled him into a career as a developer.

Throughout his 14+ years of career, Pradeep developed applications in diverse domains such as dev productivity, privacy, neural search, authentication, NLP, cryptography, data engineering, etc.

Pradeep founded two startups, authored a book, and published #OpenSourceDiscovery newsletter. For 8 years, Pradeep developed and maintained his key project - Developer Diary, a cross-platform productivity tool for developers. This long-term commitment provided him with deep insights into the evolution of various engineering and community functions. Leveraging these insights, he guided various Open Source organizations to create category-leading developer tools and foster thriving, engaged developer communities.

As a late bloomer in tech from a small town, he witnessed how the internet empowered developers from remote areas to transform their lives. This inspired him to found Invide, an invitation-only community for developers from underserved regions. Drawing from his own journey, the initiative helped over 15000 experienced developers with resources he once lacked.

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.
