How I deliver
- 1
A written plan first
Before any code, you get a one-page plan: what gets built, what "done" means for each part, the price and the date.
- 2
Your design first
You see one or two key screens in your brand before the rest is built.
- 3
Small steps you can click
New work goes to a private preview link every day. You try it on your laptop and phone, and nothing goes live without your yes.
- 4
Checked before you see it
Automated tests run on every change, and a separate review checks the build against everything you asked for.
- 5
Yours at handover
The code, the accounts and a handover document move to you: your name, your hosting, your GitHub.
About
I'm Alex. I'm from Romania and I've lived in the UK for 12 years. I started here as a plumber and worked my way up. For the last 5 years I've been a site supervisor on construction projects.
I got into AI by building voice agents for Airbnb hosts, because I knew people in that world and could see they were missing calls. Then I built one for a roofing company I knew. That's where I started using Claude Code every day, and I liked building more than anything I'd done before.
On site, nothing gets handed over without a plan, an inspection and a snag list. I build software the same way. You get a written plan before any code, tests on every change, a separate check against your brief, and a handover document your developer can actually use. I'm fast, but I don't skip the checks.
With agencies I stay in the background. Your brand, your accounts, your client.

24/7 voice receptionist for roofers
One master agent in Retell; each roofing company's name and details are filled in per call. Conversation flow, 10 tools, UK English, about $0.21 a minute, 810–1,280 ms latency.
A separate QA agent reviews the calls. On 43 real calls it caught 88% of the problems a person flagged, with 0 invented quotes.
Retell · GPT-5.1
Call automation behind the voice agent
After each call, the caller's details land in the roofer's sheet and the owner gets a text. A second flow saves the photos a caller sends into a Drive folder for that job and updates the sheet.
