Hi, I'm Morten Elmstrøm Hansen

Platform Engineer at Mind Energy | Published Author | Østjylland, Denmark

I build reliable infrastructure, write about automation, and ship tools that solve real problems. 14+ years of hands-on experience — from self-taught Python scripts to production Kubernetes platforms.


What I Do

  • Platform Engineering — Kubernetes clusters (K3s HA, AKS), GitOps with ArgoCD, Helm, Terraform, CI/CD pipelines
  • AI/LLM Integration — RAG systems, MCP servers, vector search (pgvector), Claude & OpenAI APIs
  • Python Development — Flask, FastAPI, async patterns, CLI tools — my primary language since 2012
  • Technical Writing — Published author, documentation-first approach, knowledge sharing

Published Book

PowerShell Advanced Cookbook
BPB Publications, 2024 — 684 pages, 90+ recipes
Enterprise automation patterns, Active Directory, CI/CD integration, module development, and more.

Origins — Where It Started

Before Kubernetes and AI, there were 70+ self-taught Python projects built between 2012–2019: voice assistants (before Alexa), roguelike games, P2P encrypted chat, network toolboxes, IoT with Raspberry Pi, and more. 30,000+ lines of curiosity-driven code that laid the foundation for everything that followed.
