It works when you demo it
It doesn't work when fifty people sign in at once. That's not because you built it wrong — a prototype is built to be looked at, which is a different thing from being used. I turn it into something that holds up, without you starting from scratch.
What breaks
Always the same five things
Whether the prototype was built in Bubble, Lovable, Figma or by hand. It's not the tool's fault — it's the difference between showing something and running it.
It loses data
Two people save at the same time and one of the changes disappears. Nobody notices until someone gets in touch.
The sign-in runs on trust
It keeps the curious out. It doesn't keep out anyone who knows what they're doing.
It slows down with real data
Fifty rows were fine. Fifty thousand aren't, and it's the same code.
Nobody knows what's live
You ship new versions by dragging something somewhere, and there's no way back when it goes wrong.
You're the only one who can change it
Which means it doesn't change, which means it doesn't get better.
How it works
Your product, not a new one
01
We read what you've built
Before anything is rewritten. Most of a prototype is well thought out — it's just built to be demoed, not used.
02
What carries weight gets rebuilt
Database, sign-in, payments, publishing. The parts that break silently, and that cost the most to replace later.
03
The rest comes along
Flows and screens that work stay as they are. You'll recognise your product afterwards.
04
You get the keys
The code is yours, on your own accounts, and you can ship a new version yourself. No lock-in, and nobody sitting on the passwords.
How it works
How the subscription works
One flat price
The same amount every month. No hours to approve, and no invoice that turns out bigger than you expected.
One task at a time
You put the most important thing at the top. I build it, you test it, then we move on to the next thing in the queue.
Delivered in days
Most tasks are done within 48–72 hours. Anything bigger gets broken down until it isn't.
Pause whenever you like
No lock-in and no notice period. Pause between launches and pick up where you left off.
