The app that runs a London handyman company
Handy 4 London is a handyman and renovation company. The owner is on the tools most days and works with self-employed contractors. I built the app they now use to run every job.

The problem
Jobs came in by phone, WhatsApp and the website. Quotes were written by hand. Contractors got the job details by message, photos were scattered across phones, and working out what a job actually made meant digging through all of it.
Off-the-shelf job software is mostly built for bigger companies and charged per user. This business needed something that works the way it does: one owner, a small office, and contractors who each get their own share of the job.
What I built
One app with two sides. The office sees everything. Each contractor sees only their own jobs and only what they need to do them. Customer records stay with the office.
For contractors
- Today's jobs and everything needed for them
- "On my way", "I've arrived" and a job clock
- Before and after photos on the job
- Customer signs off on the phone
- Quotes priced from the same price book
Behind the scenes
- Push notifications for new and changed jobs
- Automatic reminder the evening before a job
- Contractor pay worked out per job
- Secure logins and locked-down data
- Installs like an app, no app store needed
Inside the app

What changed
- Every job is in one place: no more hunting through WhatsApp for an address or a photo.
- Quotes are consistent: everyone prices from the same price book, so prices stay the same whoever writes the quote.
- Proof of every job: photos and the customer's signature are saved with the job.
- The owner can see the money: what each job made after contractor pay and expenses.
- Ready to grow: a new contractor is just a new login, which matters for a company that plans to hire.
How it's built
A progressive web app (React + Firebase, hosted on Vercel). It installs from the browser onto any iPhone, Android phone or laptop, updates itself, and doesn't wait for app store reviews. When a business needs a store app instead, I build and publish those too. See Money Map.
It's still growing. Most new features started as "can it also…" from the people using it every day, and that's how it should work.
