Freelance Java architect & systems integrator

I help organizations integrate and modernize mission‑critical Java backend systems — connecting silos, unlocking data flows, and turning fragmented architectures into coherent, high‑value platforms — through Java, sound architecture, and responsible AI‑assisted engineering.

Systems integrated. Value unlocked.

Freelance / remote-first (based near Århus/Aarhus, Denmark)
25+ years of software development and architecture experience — primarily Java and backend systems
M.Sc. in Electrical Engineering (M.Sc.E.E.)
Strong focus on integration, value delivery, security, performance, reliability, and operability
Broad domain experience in e.g. finance, telecom, healthcare, defence and maritime

What I do

Architecture and delivery of Java backend services (greenfield + modernization)
System integration and API design (REST/OpenAPI, messaging, event-driven)
Cloud/container deployment (OpenShift/Kubernetes, Docker)
Security and performance engineering for backend systems
Technical leadership: teaching, mentoring, review, sparring

How I work

I use GitHub Copilot and Claude Code as productivity multipliers — accelerating integration work, refactoring, and reviews without cutting corners on quality. My relationship with machine learning predates the current wave — my master’s thesis explored constrained Markov networks — so I understand the technology behind the tools, not just the tools themselves. Combined with 25+ years of Java experience, this lets me use AI critically: validate assumptions, catch edge cases, and keep integrated systems operable. All work is reviewed and tested.

Open source projects

I am the inventor and maintainer of:

Both projects have commercial users and are related to decoding safety‑ and navigation‑related digital messages from ships. The source code is available on GitHub and the binaries are in Maven Central.
