Kevin Pereira

Kevin Pereira

I'm a results-driven data professional with nearly two decades of experience dedicated to transforming data into strategic assets. My journey began in the intricate world of data and systems integration, mastering ETL/ELT processes to build robust foundations. For the past 15 years, my expertise has deepened within the Microsoft data stack, spanning traditional BI tools (SQL, SSIS, SSRS, SSAS), the extensive Azure Data Platform services, and Power BI. Crucially, the last two years have seen me at the forefront of Microsoft Fabric, pioneering its capabilities.

Beyond core data integration, I bring 8 years of hands-on experience in creating and maintaining robust CI/CD pipelines within Azure DevOps, ensuring streamlined, automated, and reliable deployments for a diverse range of data projects. This commitment to operational excellence extends to my 3 years of experience in managing and nurturing a team of Data Engineers, fostering growth and driving collaborative success.

My dedication to the data community is a cornerstone of my professional identity. As a leader with the DFW Power BI User Group, I actively contribute to growing local talent and knowledge sharing. This year, I've had the incredible opportunity to share my deep knowledge of Microsoft Fabric as a speaker at various SQL Saturday events, user groups, and notably, at both the Microsoft Fabric Community Conference in Las Vegas and in Europe.

Emiliano Pisu

Hi 👋 Folks!
I’m Emiliano Pisu, your friendly neighborhood Design Engineer.

Throughout my career, driven by my coding addiction, I’ve always stayed up to date with software development and related trends, focusing on UI, UX, Accessibility, Responsiveness, Compatibility, Scalability, and Maintainability.

My main goal is to build accessible and pixel-perfect user interfaces that enhance the user experience.

My core approach is to develop with zero dependencies, fostering creativity, learning, experimentation, and deep knowledge. This leads to solutions that not only follow trends but are also carefully tailored to the needs of clients and stakeholders.

I am deeply committed to knowledge sharing and mentorship: through my experience as Sensei @ Dev Dojo IT, I actively support those who want to grow in the frontend world and in designing accessible and scalable interfaces.

In conclusion, I’m the right person if you need a bridge between Design and Development. I live to simplify my colleagues' DevX, which is why I focus on advocating for the core technologies of the web, strictly vanilla.

Mónica Mesa

Mónica Mesa

Microsoft Data Platform MVP and proud #datalover.

I'm that person who gets genuinely excited about a well-designed Lakehouse at 9am on a Monday, and yes, I've made peace with that.

My technical home is Microsoft Fabric, end-to-end data solutions, Medallion architecture, data engineering with PySpark and Python, semantic modeling with TMDL, real-time intelligence, and governance. Power BI lives inside Fabric, and that's exactly how I treat it. Currently riding the Agentic Era wave with MCP and AI agents, because who can resist a good technical challenge?

Community is where I come alive. I co-organize Women in Fabric, because women belong on every stage, every whiteboard, and every data team, and the Fabric User Group ESP. I also co-created calendarioeventosdatos.com, a free community map of data events. I speak internationally and write at monicamesa.es.

My superpower? Making even the most technical model feel approachable, useful, and fun.

When I'm not knee-deep in data models and wild ideas, you'll find me planning the next trip, chasing sunrises on a run, or eating an irresponsible number of croquetas. I also have a weakness for costumes, if there's an excuse to dress up, I'm first in line.
And yes, I tell bad jokes. Someone has to break the ice.

Data doesn't just make us work better, it changes how we understand the world. And I'm here for all of it. 🚀

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.
