Frank is always on the move and he brings that same drive to the teams he works with. His passion lies in technology, and he stays closely engaged with the latest developments in Azure and .NET. But he also understands that technology alone isn’t enough. His strong aversion to inefficiency has made him a firm advocate for DevOps.
Over the past few years, Frank has been actively implementing DevOps practices at Luminis, helping teams embed these principles into their daily work.
His ambition goes beyond just writing code. As an architect, he focuses on helping clients improve efficiency through cloud-native solutions, always aiming for sustainable, long-term impact.
But having a good idea isn’t enough—you need to be able to share it. That’s why Frank enjoys speaking about his field, whether through blog posts or conference talks, actively contributing to the wider tech community.

Beyond Hosted Agents: Mastering Azure DevOps Scale Sets
We've come a long way with build agents on Azure DevOps, I still remember all the times I had to call the system administrators to inform him that our build server running in our office had no more disk space.
Now we have hosted agents that require zero maintenance, amazing, I use them in almost all of my projects. But what if hosted agents don't fit your use case, or you don't like giving away more money than necessary to Microsoft.
This is where Azure DevOps Scale Sets come in. Do you want to deploy resources behind your Azure firewall running 20 parallel jobs on Friday 4 pm on a 416 core machine?
No problem! In this talk I will show you how to set this up step by step in a matter of minutes.
From In-Process to Isolated, challenges and solutions for migrating Azure Functions to .NET 8
In the Azure Function roadmap, Microsoft has announced that .NET 8 will be the last Long-Term Support (LTS) release to support the in-process model. Consequently, migrating Azure Functions to the isolated worker model becomes necessary. However, this transition can significantly impact legacy Azure Function apps. In this session, I’ll talk you through the differences and how to address some of the challenges we encountered while migrating our Azure Function apps and share how I solved them.
Beyond AAD B2C: The Future of External Identity in Azure
Azure AD B2C has long been the go-to solution for managing external identities in Azure. It is powerful and scalable, but not without trade-offs. Developers often had to choose between the simplicity of built-in user flows or the steep complexity of custom policies to unlock advanced scenarios.
Now, Microsoft is making a clear shift. Azure AD B2C is being phased out and will be retired within the next five years. Its replacement, Microsoft Entra External ID, introduces a new model for managing external identities. The goal is to reduce complexity, improve the developer experience, and better support modern identity use cases. In this session, we will explore why this change is happening, what is already known about the new platform, and what it means for both new projects and existing B2C implementations that need to plan for the future.
Drawing from real-world B2C implementations, we will compare both solutions, highlight what Entra External ID does differently, and show how it simplifies previously complex scenarios. Along the way, I will walk through practical examples so you can see what it looks like in action, both conceptually and in code, including how to integrate it into automated CI/CD pipelines and infrastructure workflows.
