Freelance Business Central developer & technical architect
Business Central extensions, built to last¶
I'm Job Louage. I design and build AL extensions, Microsoft Marketplace apps and developer tooling for Microsoft Dynamics 365 Business Central: from the architecture to the release.
What I do¶
-
Technical architecture
Extension designs that stay maintainable as your solution and the platform evolve: clear interfaces, events and upgrade paths.
-
Extension development
AL extensions from spec to production, test-driven and ready for Business Central online, including Microsoft Marketplace apps.
-
Integrations
Connecting Business Central to the services around it, such as external storage on Azure Blob Storage or SharePoint.
-
DevOps & AI-assisted development
AL-Go for GitHub pipelines and GitHub Copilot agents that help teams ship Business Central code faster and more consistently.

What clients say¶
Job handled the technical side of our move from an outdated on-premises Navision to Business Central online: the connections with our external systems and the developments that automate our processes. He combined expertise, availability and a pragmatic approach: clear advice and targeted solutions, without unnecessary complexity. Our accounting now runs more smoothly, and we understand our flows well enough to keep optimizing.
Job helped us take a sister company live on Business Central within three months. He met every deadline and focused on substance and structure rather than on selling. The go-live was so well structured that our customer barely noticed the handover.

AL Interfaces with Default Implementations
September 22, 2026
One of the most significant architectural improvements in Business Central 29 is the ability to add default method implementations to AL interfaces. This seemingly simple feature unlocks powerful patterns for managing complex extension architectures, particularly when you're building platform-level solutions or managing multiple interdependent extensions.
