David Kjerrumgaard

David Kjerrumgaard

David Kjerrumgaard is a Developer Advocate at StreamNative and a committer on the Apache Pulsar project, where he focuses on the intersection of real-time data streaming and agentic AI. With over a decade of experience building distributed systems at scale, he helps organizations connect AI agents to the live data and tools they need to operate in production.
David's current work sits at the foundation of an emerging discipline he calls context engineering — the practice of designing data infrastructure for AI agents. He explores how streaming platforms like Apache Pulsar and Apache Kafka serve as the event-driven backbone for multi-agent systems, how the Model Context Protocol (MCP) extends to streaming primitives, and how lakehouse-native architectures make real-time agent infrastructure both reliable and cost-efficient.
He is the author of Pulsar in Action (Manning) and co-author of Practical Hive (Apress), and an active committer on Apache Pulsar with contributions to Apache NiFi. As an internationally recognized speaker, David has presented at conferences worldwide — including NDC London, ApacheCon, Community Over Code, Devoxx, and Data Streaming Summit — and was named a Sessionize Most Active Speaker for 2024.

David's career spans hands-on engineering and technical leadership at companies that have shaped modern data infrastructure. He served as Principal Software Engineer on Splunk's messaging team, focused on real-time data analytics at scale. Prior to Splunk, he led solutions architecture at Streamlio and served as Global Practice Director at Hortonworks, where he architected enterprise-scale streaming and big data platforms for Fortune 500 organizations across financial services, telecommunications, and manufacturing.

His talks combine deep technical content with the practical lessons learned from years of production deployments. Whether explaining how to govern AI agents at the data layer, designing event-driven multi-agent orchestration patterns, or wiring live data streams into LLM context windows, David's sessions are grounded in working code and real-world architectural tradeoffs.
David is passionate about open source as the foundation for the agentic AI era. He believes the same open standards, durable infrastructure, and community-driven evolution that powered the rise of modern data streaming will define how the next generation of AI agents reaches production. Through his writing, speaking, and code contributions, he works to bridge the streaming data community and the emerging agent ecosystem.

Tomas Prokop

Tomas Prokop

I'm a Microsoft MVP in Business Applications who thinks the Power Platform community spent a decade treating "code" like a swear word. Now AI is generating JavaScript, React, and Python faster than most can review it. The real skill isn't generating code - it's deciding what NOT to build.

My journey in IT started in high school with ASP.NET and Android apps. I got serious about Microsoft technologies through the Student Partners program and joined the Czech Microsoft team in 2016, supporting startups through BizSpark. That's where I discovered Dynamics XRM and got hooked on the platform's potential - and its pain points.

Fellow MVP Jan Hajek and I started NETWORG to build Microsoft business applications the way professional developers expect: Dataverse plugins in C#, PCF components, custom connectors, automated testing with Playwright, and Azure DevOps pipelines that deploy code, infrastructure, and configuration as one unit. We adopted CI/CD and DevOps practices early because we kept hitting the ceiling of what point-and-click tooling could deliver.

LLMs are excellent tools for working with unstructured information - but treating them like magic hurts adoption more than it helps. I focus on what actually works in production: architecture patterns documentation doesn't cover, real failures and workarounds, and why your AI-generated code still needs someone who understands what it's doing.

My sessions cover pro-developer experiences: Git monorepos, CI/CD pipelines, security internals, governance at scale, and AI-assisted full-stack development. If you've built a Power Platform app that grew beyond Excel automation into something mission-critical - and realized the tooling doesn't match the complexity anymore - these sessions are for you.

I organize the CZ/SK Power Platform User Group meetup at the Czech Microsoft office. Join us at https://ppug.community.

Christian Alexander Schreiber

Christian Alexander Schreiber

Christian Alexander Schreiber is the CEO & Founder and Lead Architect of nVibes, a next-generation European social platform based in Dresden, Germany, built around one central idea: Real Vibe. Real People.

With nVibes, Christian is building a social infrastructure for real human connection — a platform designed not for endless scrolling, but to help people feel less alone, find belonging, build trusted communities and create meaningful moments beyond the screen.

https://nvibes.de brings together social interaction, communities, events, real-world activities and intelligent digital experiences while placing privacy, trust, responsible AI and European digital sovereignty at the foundation of the platform.

With more than 30 years of experience in IT consulting, software architecture, Microsoft technologies and digital transformation, Christian combines deep technical expertise with the perspective of a technology founder building a new digital platform from Europe.

His work focuses on the intersection of human-centered technology, responsible and agentic AI, privacy-by-design, digital identity, platform trust, cloud architecture and European technological sovereignty. He explores how AI and modern platforms can strengthen human interaction instead of replacing it — and how technology can create genuine value when it is designed around people rather than attention.

Christian also speaks about AI-ready Azure architectures, responsible AI adoption, secure digital platforms, agentic systems and the practical realities of turning an ambitious technology vision into a real product.

As an international speaker, he brings together strategic leadership, hands-on architecture and real-world startup experience. His sessions are practical, technically grounded and driven by a clear conviction:

The future of social technology should not be about keeping people on a screen. It should help bring people together.

nVibes — Real Vibe. Real People.

Please note that Sessionize is not responsible for the accuracy or validity of the data provided by speakers.

Most Active Speakers 2024

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 2024.

The 3% is calculated from the pool of all speakers that have at least one accepted session in year 2024. We don't include inactive speakers or speakers that had no accepted sessions during the year. There are around 38,000 unique accepted speakers this year, the 3% is 1036. 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 2024. 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.
