I started my career in a service desk role, which quickly sparked my interest in how technology is built, operated, and scaled. From there, I moved into data center hosting where I gained a solid understanding of infrastructure, reliability, and what it takes to keep critical environments running. I don’t have any formal education in IT, but I’ve always been a lifelong learner who grows through curiosity, hands‑on experience, and a drive to constantly improve.

Almost a decade ago, I discovered my passion for the cloud and specialized in Microsoft Azure. Since then, I’ve focused on modern Ops, platform engineering, and enabling teams by taking ideas from early concepts into secure, scalable, production‑ready solutions. Over the years, I’ve expanded my expertise across data, AI, and IoT and IIoT, and I most often work with clients in the role of Solution Architect, helping them design and build practical, outcome‑focused architectures tailored to real enterprise needs.

I’ve worked across a wide range of domains including defense, public sector, manufacturing, and energy, which has shaped how I approach architecture, security, and complex enterprise environments. I also contribute to the open‑source and enjoy collaborating with others to advance how we build and deliver modern solutions.

🗣 Sharing knowledge is a big part of who I am. I’m passionate about public speaking and mentoring, and I enjoy helping others grow by making technology more accessible and actionable.

Today, I work with enterprise‑scale AI, data, and IIoT solutions with large companies, turning ideas into real, measurable impact.

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.
