During the day I’m an Enterprise Architect, while I love writing at night when I get a hot cup of tea!

Rik helps organisations use Cloud better as CEO and co-founder of Zure UK. Whether that is a new adoption where governance and management are key, or an application modernisation project where technology choice and team knowledge are important factors in success.

Now he spends more time working with his customers' management, sharing that breadth of experience and learning.

Porto-based and powered by chaos, I split my time between Portugal, Chicago, and wherever the next conference or suspicious packet capture happens to be. Equal parts cybersecurity architect, honeypot wrangler, and frequent flyer with a questionable relationship to gravity, I run a growing Honeypot Empire designed to annoy attackers around the globe!!

When not speaking at security conferences or building deceptive little digital trapdoors for internet goblins, I can usually be found hopping continents, mentoring folks in cybersecurity, sipping dangerously good tequila, or voluntarily jumping out of perfectly functional airplanes. Sasha the Dancing Flamingo still supervises operations with chaotic authority and absolutely believes she deserves root access.

Erissa Duvall

Erissa Duvall

Everyone has their niche in the world where they find the most joy and fulfillment. For me that has become Accessibility. Some of my experience comes from my personal ordeals I have gone through as I have steadily learned more about what makes my brain tick and what makes my joints throw a temper tantrum. My professional experience has helped me along the way because it is where I learned just how diverse the options were for accommodations, treatment, and more.

I was initially thrown into the deep end during my amazing journey with the American Printing House for the Blind's Internal IT department. I gained insight to some of the struggles caused when environments, processes, technology, and attitudes are not accessible. However, I also experienced great joy every time I managed to help make someone's day easier by helping them be more independent and confident in themselves. Since then, I have held many other Accessibility related roles and made it my mission to spread Accessibility awareness. I've done so through by improving Code Louisville's Accessibility policies and coursework as a mentor, speaking at domestic & international events, providing support online, and so much more. I plan to continue to do what I can for as long as I am able.

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.
