About

Hi, I’m Magnus Johansson

I’m a freelance software developer focusing on the Microsoft technology stack, and InsomniacGeek is where I write up the things I learn, build and troubleshoot — usually late at night, which is how the name came about.

The goal of this blog is simple: when I solve a problem that took me a while to figure out, I write it down so the next person (often my future self) doesn’t have to start from scratch. Most posts come straight from real, hands-on work rather than rehashed documentation.

What I work with

Over the years I’ve worked across a broad slice of the Microsoft ecosystem and the wider developer tooling world. The topics you’ll find most of here are:

  • Cloud & DevOps — Microsoft Azure, Azure DevOps, self-hosted build agents and CI/CD pipelines
  • .NET — C#, the dotnet CLI and tooling, ASP.NET
  • Cross-platform & mobile — Flutter, Android SDK, Xamarin
  • Automation & Windows — PowerShell, the Windows registry and developer environment setup
  • IoT & electronics — Raspberry Pi, microcontrollers, lab equipment and home tinkering
  • AI & developer tooling — including building a Model Context Protocol (MCP) server to let an AI assistant drive my oscilloscope

Experience & credentials

I’ve been building on Microsoft technologies for a long time and have been an active member of the developer community for just as long. A few places that reflect that:

Beyond code

When I’m not at a keyboard, my biggest passion is music — I play the bass guitar. I also enjoy electronics and retro computing (I have a soft spot for the Commodore Amiga), and getting outdoors hiking in the Swiss mountains.
