Engin Diri

As a Senior Solutions Architect at Pulumi with over 15 years of experience in the IT industry, including roles at the Schwarz Group and W&W Versicherungen, I bring extensive expertise with an end-user and enterprise focus. Currently working for a startup while collaborating with enterprise clients has further enriched my experience!

I began my career as a Java backend developer, transitioned to frontend development, and ultimately specialized in CI/CD and DevOps. Working with ANT and Cruise Control to switch to Jenkins and Microsoft Team Foundation Server added some traumas on top! But as they say, what doesn't kill you makes you stronger.

I have now embraced the dynamic world of DevOps and Platform Engineering, leveraging cloud technologies and Kubernetes.

Recently, I have been exploring AI to find ways to make myself redundant in the future.

Nicola Guglielmi

Nicola Guglielmi

I operate at the intersection of bold vision and brilliant teams. As a Principal Cloud & AI Strategist and Fractional CTO, I partner with companies to architect future-proof cloud solutions and build the high-performing engineering teams needed to execute them.

With over a decade of hands-on experience in Digital Transformation, I specialize in Google Cloud Platform, Generative AI (Vertex AI), and complex multi-cloud architectures. I don't just talk theory, I have built Cloud Business Units from scratch and led mission-critical migrations in fast-paced sectors like Oil & Gas.
My philosophy is simple: an elite strategy is useless without an elite team to execute it, so I build the team first, knowing that the results will follow.
As a passionate advocate for open knowledge, I am a Google Cloud Authorized Trainer, a Google Developer Expert (GDE) for Cloud, and the Community Lead for GDG Campobasso.
Whether I am live-coding a Gen AI agent or sharing insights on the dynamics of engineering leadership, I bring energy, clarity, and deep real-world experience to the stage. I love connecting with people who are eager to challenge the status quo and push the boundaries of what technology can solve.

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

Most Active Speakers 2023

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 2023.

The 3% is calculated from the pool of all speakers that have at least one accepted session in year 2023. We don't include inactive speakers or speakers that had no accepted sessions during the year. There are around 25 thousand unique accepted speakers this year, the 3% is 771. 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 2023. 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.
