## About

```text
At Kollab, I replaced a legacy Silverlight system with a new Blazor application and moved the solution from Azure DevOps to GitHub, with one-click deployment through GitHub Actions. I also introduced shared AI-assisted development workflows and built a Claude-based intake flow that turns requests into Jira tasks for developer review and customer approval.

At Netcompany, I was technical team lead on systems for the Danish Ministry of Immigration and Integration. I owned solutions across .NET and Angular that handled sensitive personal data under strict GDPR and EU data-residency requirements, and included API integrations with other government agencies.

I’ve also built Denmark’s pavilion platform for World Expo 2020 Dubai and developed VR applications in Unity for architecture research at Aalborg University. My work spans C#/.NET, TypeScript, and SQL Server, with experience in architecture, CI/CD, and customer-facing technical delivery.
