About

Hi, my name is Dirk Menkveld and I build software — and I’ve spent fifteen years deciding what should get built. These days a growing part of that is agentic engineering: systems where a model does real work rather than just answering questions.

I founded Koppa, a fantasy sports company whose platform I designed, wrote and still operate: a Laravel API, a Flutter app, a CakePHP web application and Kubernetes underneath, serving 150,000+ registered users across 15 countries. If you want the technical detail, I wrote up the full architecture.

Alongside that I’ve worked as a freelance product owner and product manager for Yunoo (co-founder), Fox Sports, NEP, YogaHabits, Node1, Shopify, Klarna, Ubideo, Studio Henk, Livewords, Mediahuis, AgnoPlay, Dumpert, Coinmerce, ANWB, Essent and ID&T / Superstruct. Go to the projects overview if you’d like to know more.

Those two halves are the point. I estimate honestly because I’ve had to build it. I build the right thing more often because I’ve had to own the roadmap. Most people you can hire do one or the other.

What I do

Build — Laravel and PHP 8, Flutter and Dart, Vue and Nuxt, Python, MySQL, Redis. APIs, mobile apps and web platforms that carry real traffic. See full stack.

Run — Kubernetes, Docker, Google Cloud, AWS, Cloudflare, GitLab CI/CD, Terraform, Netlify. Plus the monitoring that tells you whether any of it is working: Sentry, Grafana, New Relic, Hotjar.

Automate — AI agents and MCP servers, plus n8n, Zapier, HubSpot, systeme.io and Tally. Connecting the systems a business already runs on — CRM, marketing, billing, support — and putting an intelligent step in where it actually pays off, so the handovers stop being someone’s manual job.

Lead — Scrum, Kanban, JIRA and Confluence, Design Thinking, discovery, roadmapping and stakeholder management. Product ownership with an engineer’s sense of what things cost.
