What I'm looking for

I’m looking to build and extend Business Central with AL and .NET, delivering reliable ERP integrations (API/EDI), high-performance SQL, and maintainable architectures—while mentoring teams and owning end-to-end delivery.

I’m a Microsoft Dynamics 365 Business Central Developer with 15+ years specializing in AL development, Dynamics 365 Business Central/NAV, and .NET technologies. I focus on translating business requirements into robust, maintainable solutions that stand up in production.

I’ve delivered end-to-end ERP work, including API & EDI integrations, and migrations from Dynamics NAV to Business Central. I also build supporting tooling and optimize databases—so systems stay reliable as complexity grows.

In recent roles in Germany, I designed integration endpoints (EDI/JSON request-response handling), automated Amazon Seller Central integrations, and implemented custom AL code and Business Central extensions to improve operational workflows. I also managed SQL Server environments and created .NET helper applications for on-prem Business Central.

I bring a technical leadership mindset—mentoring teams, coordinating delivery, and partnering on technical specifications across Dynamics 365 and Power Platform. My certifications (MB-800, MB-820) reflect my commitment to being both a builder and a trusted advisor.
