Michiel Hamers

Michiel Hamers

Hi, I’m Michiel Hamers, a Principal Cloud Expert, Implementation Manager, Trainer, and former Microsoft MVP with over 25 years of experience in the Microsoft ecosystem.

Since 2000, I’ve been helping organizations successfully adopt and optimize Microsoft technologies, with a focus on Azure, cloud architecture, performance, and cost management. As a Microsoft Certified Trainer (MCT) and experienced consultant, I bridge strategy and execution, guiding both public and private sector teams through complex technical transformations.

I regularly speak at international conferences such as Developer Week, PowerShell + DevOps Global Summit, Global Azure, AzConf Chennai, Azure Fest, DevConf APG, FutureTech, and Dutch Cloud Meetup. I’m passionate about delivering hands-on workshops and tailored in-company trainings, helping teams sharpen their Azure, automation, and application lifecycle skills.

My mission is clear: help people and organizations get the most out of the cloud, with control, clarity, and confidence. Whether coaching colleagues, giving workshops, or advising on cloud-native modernization, I combine deep technical knowledge with a pragmatic, people-focused approach.

When I’m not working, I enjoy life with Sandra, cooking, traveling, and spending time with family and friends. For me, technology is about empowering people, not just systems.

Let’s connect and build something great together.

Ivan Pesenti

Ivan Pesenti

I'm Ivan Pesenti. A passionate gopher who has been working in the software industry since 2014.

I'm a software engineer focused on server-side programming. Throughout my career, I've always been accompanied by two obsessions: testing and writing secure code. I consider myself a detail-oriented person.

My career took a turning point in 2021 when the Go programming language crossed my path. Since then, I've fallen in love with it.

I believe in empathy, kindness, mutual help, growth, determination, and trust. These values have led me to give back to the community through speaking, coaching, writing, and more. Helping others is one of the most satisfying experiences I've ever had.

During my free time, I train my body, play football, watch anime, and hang out with family and friends.

One of my favorite quotes is: "Hard work beats talent."

Javier Ramirez

Javier Ramirez

As Head of Developer —and Agent— Relations at QuestDB, I help developers make the most of their (fast) data. These days that increasingly means AI agents: I make QuestDB easy for an agent to use through skills, MCP servers, machine-legible docs, standard interfaces like SQL, REST, and Parquet, and a cookbook of ready-made recipes, so agents produce correct, fast results with as few tokens as possible. I also make sure the core team behind QuestDB listens to absolutely every piece of feedback I get, and I facilitate collaboration in our open source repository.

I love data, big and small, and I enjoy processing it with streaming engines, ML models, SQL, NoSQL, graph, in-memory, and time-series databases. I prefer distributed, scalable, always-on systems.

Before working at QuestDB I spent over 20 years developing software professionally and sharing what I learnt with the community, including three years as a Developer Advocate at AWS and five years as a Google Developer Expert in Cloud. I've spoken at events in over 25 countries, mentored dozens of start-ups, taught for 6 years at different universities, and trained hundreds of professionals on cloud and data engineering.

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.
