About

James at Dividend Solo

One developer, fifteen years of QA, and the writer behind every post on this site.

Before this

I spent fifteen years getting paid to break other people's software on purpose: insurance, e-commerce, accounting. Which is how I learned what a product looks like from the side that finds the parts the builder never touched.

What I ship now

I build and ship my own, solo, with a crew of AI agents doing the parts one person cannot get to: ZeroPhase, Situation, RepSheet, and omarchy4mac. A SEAL prep program, a geopolitical terminal, a workout tracker that reads a photo of a plan, and Omarchy for the Mac. If something of yours is stuck, the builds I take on are fixed price and fixed date: see the six builds.

What I write

The blog is solo SaaS, macOS and AI, in public. Every post is written after the thing it describes shipped, so it carries the stack, the numbers, and the parts that were harder than expected — including the ones that did not work.

The letter

Sunday Signal is one email, every Sunday morning: the real numbers from building one-person apps, and one lesson you can use, in under five minutes. The box is in the footer below, and every issue carries a one-click unsubscribe link.
