What they did
A client needed a tool to post content on a schedule to about 9 different social networks. They built it as a .NET Razor web app with a SQLite database, working with Claude by building up the functionality in layers and testing each layer as they went, including a driven browser for posting to Twitter before its API reopened.
How it went
It took about two hours with Claude, versus the roughly a month they estimate it would have taken to write by hand in the old, pre-AI style. It’s been running flawlessly for months without a single error, though they still check on it every morning.
Try it yourself with Claude
Pick a repetitive multi-step task you could automate, like posting content to several platforms on a schedule. Work with Claude in layers: build and test one piece of functionality at a time (fetching content, formatting it per platform, posting, logging) before moving to the next, rather than asking for the whole system at once. Keep testing each layer as you add it.

A technical SEO and UX audit for a new client site normally takes the writer 3.5 to 7 hours. Claude pulled client info from OneDrive, ran the audit, drove a remote PageSpeed tool, and produced a Word report in 0.5 hours.
Public government data is hard to get at. Claude built sites that present it clearly and email it weekly, then review their own SEO and fix the day's glitches. Subscribers are trickling in.
In a meeting about a bug in an app they didn't own, they told Claude to find out if it was user error, notify the user, and tell the developer what to fix. Fifteen minutes later, the developer asked: today or Tuesday?
After $45 in GitHub Actions overage in one month, a solo founder put an idle homelab to work as CI runners, with Claude making it easy to set up. Daily spend dropped from $2-4 a day to under $0.25.
A first homemade synth has 36 hall-effect keys and buttons and 7 rotary encoders. The firmware started by hand, then gentle prodding at Claude got everything needed much faster. Rev 2 of the PCB is nearly done.
A browser game where you answer with a power of ten leans on Claude for code and content: fact checking answers, writing explanations, and inventing new questions.
