About

Alex Larsen

I have over a decade of experience building software and leading teams of developers. These days I use AI tools, agents, and workflows to move from idea to launch dramatically faster — without giving up reliability.

The most rewarding projects guide a business from a legacy system to a modern platform that makes life easier and is built to last. You get a single dedicated developer from first strategy through final launch.
