Aditya Raj Singh (Adi)

MD by title, AI engineer by habit. Give me a week inside your business. I'll find the job nobody wants to do and hand it to an AI agent.

Try my Mac apps Read what I'm learning See every PR I've opened

Contributing to 28 open-source projects whenever I get the chance.

What I play with here

  • Forward deployed engineering. I learn how a team really works before I write code, then ship the AI agent, MCP server, integration or n8n automation that removes the manual step, and make sure people actually use it.
  • Open source, straight from my homelab. I self-host my whole stack on Proxmox. When an app I run breaks, I find the root cause and send the fix upstream.
  • Mac apps and MCP servers. Small tools that fix my own daily annoyances, released free and open source.

Apps I just open-sourced

Folderglass Stars

Folderglass showing the largest files in a folder

Press Space on any folder in Finder to see its real size, file types, largest and newest files, git status and README.

brew install justadityaraj/tap/folderglass

Switchboard Stars

Switchboard's browser picker

A menu-bar app that opens every link in the right browser, Chrome or Brave profile, or private window. Windows port planned.
