Hey, I'm Alejandro 👋

About me

Most of what I build is software for hardware I own: my multimeter, my 3D printers, my firewall, the switches on my walls.

  • I write a lot of C# and .NET: Windows desktop apps, cross-platform apps with .NET MAUI, and an Outlook add-in or two
  • I also solder, flash ESP8266 boards and write firmware in C and C++
  • My homelab runs OPNsense, Home Assistant, Klipper and a lot of Docker containers
  • Recently I've been adding MCP servers so AI assistants can talk to that hardware

Featured projects

A companion app for the EEVblog 121GW multimeter on iPhone, iPad, Mac, Android and Windows. It draws the meter's LCD, presses its buttons remotely, logs and graphs readings, exports CSV, and includes an MCP server so Claude can read the meter.

A GUI for Windows' mklink, so you can make symbolic links, hard links and junctions without the command line. It's my most popular project.

Pretends to be a UniFi Security Gateway, so a third-party router running OPNsense, pfSense or OpenWrt shows up in the UniFi controller with its stats.

Sends WiFi credentials from a Flipper Zero to a Linux server over infrared. Point, send, connected.

Other projects
