Made by David, Built with AI

Nine things I built with AI, and what each one taught me.

Websites, an Android app, a smart home screen, two working agents and a team of agents that looks after the rest, all built with Claude. I’ve captured how each works, the techniques that mattered, and what I would do differently next time.

The ‘Defender’ sites

Planning Defender, Section 20 Defender and School Place Appeal each turn a letter or notice (i.e. something that would usually require research and often legal expertise to respond to) into a structured, evidence-led pack. Claude built them from first idea to launch, and a second AI checked the content.

02Custom launcher and home controlIn daily use

Fire TV home screen

A custom launcher for four Fire TV sticks that opens my apps and runs the house from the remote. A Home Assistant bridge lets it control a vacuum that Homey Pro cannot.

Job search agents

Each morning an agent checks about eighty sources, reads every advert and scores it against my profile, then emails me the best with reasons.

Recruiter tracking agent

An agent that reads my inbox each morning, keeps a full audit in a spreadsheet, works out who I need to follow up with and creates an initial draft of those emails for me. It also helps prepare me for the day's meetings by creating a pre-read ahead of each of my meetings.

05Web app and Android appIn use

Pension Planner

Enter what a household earns, owns and spends, and see whether the money lasts. The report is built by plain code with no AI call, and a separate AI reviewed it.

06Web app and Android appIn use

Star Chaser

A personal tracker for visiting Michelin-starred restaurants, filled by parallel research agents and checked by scripts. One source file builds both the web and the Android app.

‘butterflai’ website

A nine-page static site whose look comes from one rule: every image is generated from written brand guidelines.

The agent team

Nine agents with separate jobs look after my other projects: they find improvements, merge them into one plain-English backlog, build what I approve and test it. Nothing is committed, published or paid for without my say-so.

09Portfolio site with its own safety checksLive

This website

One file of copy feeds every page, and a checker stops dashes, names, numbers and keys from reaching the page. I edit the words in Word, Claude built the site and the agent team keeps improving it.
