open to new roles · Aarhus, Denmark
I build the machinery that makes software teams faster and safer: developer experience, CI/CD and quality gates, platform tooling, and AI that actually ships to production.

Fast feedback loops, sane defaults, tooling that removes friction instead of adding ceremony.

Read more →Paved roads: pinned toolchains, scaffolding, config-as-code and policy-as-code.
Read more →LLM features in production, agentic dev workflows, and guardrails that fail safe.
Read more →Generative-AI product enrichment & room visualization for Shopware 6
A production Shopware 6 plugin that turns product images into multilingual copy, SEO, categories and tags with generative AI, and lets shoppers see artwork on their own wall before buying. Designed, built and deployed as sole developer.
A polyglot engineering gate for AI-assisted development
One deterministic quality standard - format, lint, types, tests, coverage, security - enforced identically while an AI agent edits, before push and in CI. Reusable GitHub Actions workflows, mise templates and a Claude Code plugin, released as versioned open source.
Near-free GitHub issue triage with confidence-gated escalation
A GitHub Action that labels every new issue with TypeSafe AI's Jev in milliseconds for fractions of a cent - and escalates only the ones it's unsure about to a human or a real LLM.
A fail-safe guardrail for LLM agents' tool calls
A TypeScript library that vets every tool call an agent proposes through Jev before it runs - allow, block or hold for a human - so an autonomous agent can't rm -rf your box on a bad hunch.
jq for judgment - bulk classification at pennies per 10k rows
A CLI that streams JSONL/CSV rows through Jev and returns typed classification and score columns plus a confidence field, flagging low-confidence rows for review.
AI job-application platform - from posting to tailored CV
A Spring Boot (strict hexagonal) + Angular platform that ingests job postings and generates tailored CVs and cover letters with ATS match reports, backed by Postgres full-text and pgvector semantic search.
A bilingual technical dictionary you can explore as a map
About 420 security, CS, AI and platform terms in English and Danish, linked by typed, sourced relationships into a knowledge graph with a 2D/3D explorer, plain-language explanations and quizzes.
One React codebase, running on the web and as an LG webOS TV app
A TMDB-powered movie and TV browser that aggregates ratings, shows where titles stream in your country and - on TV - deep-links straight into the streaming apps. Same React tree for mouse and TV remote.
Spin a wheel, settle movie night
Filter, spin a 12-slot wheel and get a title plus where it streams. A static React frontend with a hardened serverless TMDB proxy - per-IP rate limiting, a path allow-list and edge caching.

A new home for my work and writing, and a quick tour of what this blog can render.
Why I stopped treating CI and "AI coding standards" as two separate things - and what Foundry does instead.
