Message

At MindEnergy, I'm architecting the migration of an enterprise Vertical Slice Monolith into distributed, event-driven microservices with Apache Kafka. I also design and optimize RESTful APIs for electricity market trading workflows.

Previously, at Systemate A/S, I delivered full-stack features for energy infrastructure and master data management platforms, using Blazor and C#.NET Core. Across my work, I've developed SaaS products, API integrations, and automated testing suites.
