Hi, I am
Asger Weirsøe
Computer scientist & Technical Solution Architect
M.Sc. in Computer Science from Aalborg University and Technical Solution Architect at Digisense A/S. I have spent my career on Danish national e-invoicing infrastructure, where I have led the response when production broke and built the processes that make the next response better. In my spare time I run my own Proxmox homelab, tinker with AI projects and get on the air as a radio amateur (OZ0AGW).
Incident response & compliance
Led incident and vulnerability response on Danish national e-invoicing infrastructure, and built an ISMS around ISO/IEC 27001 with escalation and post-incident review.
E-invoicing & architecture
Technical Solution Architect at Digisense A/S, working on Peppol, NemHandel and Oxalis. Before that, tech lead on NemHandel at CGI.
Self-hosting, AI & full-stack
A Proxmox homelab with around 50 containers and VMs behind SSO (Authentik), and projects from Java, Go and Python to TypeScript and LLM-driven workflows.
