refactor: split 1,200-line dashboard into a tested billing module

-const data: any = await fetch(`/api/sub?id=${id}`).then(r => r.json())
-if (data && data.plan && data.plan.status == 'active' || data.trial) {
+const { plan, isActive } = useSubscription(userId);
+if (!isActive) return <UpgradePrompt plan={plan} />;
return <BillingCard plan={plan} />;

The problem

Your app doesn't suck.
The code underneath does.

Every vibe-coded app hits the same wall: it works, users show up, features multiply — and the code underneath quietly turns into spaghetti.

The spaghetti compounds

Every AI-generated feature stacks another layer nobody fully understands — including the AI.

“Why did fixing login break checkout?”

The fix is expensive

A senior engineer costs $150K+ a year — and cleanup always loses to new features.

“We’ll refactor after launch.”

You have users to serve

Every hour refactoring is an hour not spent building what they asked for.

“I’m scared to touch that file.”

The solution

A senior engineer.
For a flat monthly fee.

We untangle your codebase while you keep shipping — one clean, tested pull request at a time.

Keep shipping features

You focus on the product. We work through your cleanup queue, one task at a time.

Founders who stopped fearing their own code

What happens when a senior engineer quietly works through your cleanup queue.

“I built our MVP with Cursor over a weekend and it got real users faster than I expected. Six months later I was afraid to touch it. Within a few weeks of cleanup PRs, I'm shipping features again without breaking checkout every other deploy.”

The human in the loop

Picture of CodebaseCleaners founder, Olivier Colas

Hi, I'm Olivier 👋

I've spent 10+ years shipping production code, and I'm obsessed with clean code and making things more efficient. AI tools are incredible for getting to v1 — I make sure v2, v3 and v10 don't collapse under their own weight.

Every pull request is reviewed by me personally. No outsourcing, no juniors learning on your codebase.

Because it wrote the mess. AI tools are great at greenfield and poor at archaeology — without tests and full context, they rewrite working code and break things quietly. We clean with a human in charge: small pull requests, tests attached, no big-bang rewrites.

Your first clean PR could land in 48 hours.
