Hello! I'm Tomas Prokop, a Microsoft MVP in Business Applications. My journey in IT began back in high school, when I discovered my love for programming through web and mobile application development. I worked on projects with ASP.NET and Android apps development early in my career.

My introduction to Microsoft technologies came through the Microsoft Student Partners program, and I've been an active participant in local community events ever since. In 2016, I had the incredible opportunity to work at the local Czech Microsoft team, where I supported startups in maximizing their use of Microsoft tools through the BizSpark program. It was during this time that I discovered Microsoft Dynamics, and I was instantly captivated by the platform's potential and the challenges faced by customers and the Microsoft Partner ecosystem.

Shortly after, my fellow MVP Jan Hajek and I decided to start our own business called NETWORG, focusing on consulting and developing Microsoft business applications. This venture coincided with the introduction of Microsoft Power Platform and the heart of it – Microsoft Dataverse, which we believed was the perfect tool for developing line of business apps and automating business processes. As our firm grew, we continued to adopt and leverage cutting-edge tools and processes, such as CI/CD and DevOps, to ensure the highest quality for our clients.

With years of experience in Microsoft Power Platform and .NET systems on Microsoft Azure, I am committed to sharing my knowledge and helping others succeed in the world of Microsoft business applications.

I focus on Pro Dev experiences in Power Platform. My projects use both client-side and server-side extensibility of Power Apps, custom connectors, external Azure services, automated testing and all of it delivered through advanced Azure DevOps ALM. My background is in Dataverse, former Dynamics CRM/XRM, .NET and Azure used on wide range of projects.

Connect with me online or visit the Czech Microsoft office for our monthly Power Platform meetup. Register at https://ppug.community to join the fun!

In 2015, after having spent over ten years as a Software Developer and Architect with Microsoft technologies, Mathias Thierbach moved into the Microsoft BI space. He soon landed on Power BI, but also realized quickly that the development and engineering tools and practices were nothing like the ones well established in software development. This is how pbi-tools started as a project, the only complete source control solution for Power BI.

During seven years of leading a data management team at YouGov, he experienced the benefits of those efforts every day. Having open sourced the project in fall of 2021, Mathias spends a lot of his free time bringing source control and DevOps practices to the wider Power BI community now.

In addition to his open source engagements, Mathias cares deeply about his role as an enterprise technology leader. Like many, once having started as a single contributor technologist, he had to pivot significantly when he moved into a manager role, responsible for building, stabilizing and growing a team of data engineers, analysts and architects. Mathias is now passionately sharing the many experiences and learnings that came out of that journey with the community.
