Your
Cursor
app is broken.
We fix it.

You built it fast. The demo looks great. But now it crashes, the auth is broken, and every fix creates two new bugs. We turn AI-generated code into apps that actually work in production.

We fix apps built with every AI coding tool. If AI wrote it, we can ship it.

From “Works on My Machine” to
“Works in Production.”

We look at your code, find what's actually breaking, and fix the parts that matter. You don't start over. You don't get a lecture. You get a working app.

3. You Ship With Confidence

AI Gets You 70% There.
We Handle the Other 30%.

The first version looks amazing. Then real users show up. Logins break. Pages crash on mobile. The database slows to a crawl. That last 30% is where apps go to die. Or where we come in.

Codebase Rescue

Right now your app is a maze. Same function written three different ways. Imports that go in circles. Components nobody uses anymore. We clean all of it up.

Production Hardening

AI tools build the happy path. Real users take every other path. We add the stuff AI skips: error handling, input validation, rate limiting, and auth that actually locks down.

Rate Limiting

429 throttle configured on all /api/* routes · 100 req/min per IP.

Input Validation

XSS & injection guards on 12 form endpoints.

Architecture Review

We look at how your whole app is put together, find the weak spots, and give you a clear plan for what to fix first.

API & Database Repair

Your app works fine with 10 users. With 1,000 it crawls. We find the slow queries, add the missing indexes, and fix the endpoints that break under real traffic.

Ongoing Retainer

Need us on speed dial? We offer monthly plans for founders who ship fast and need someone to keep things running.

Deploy on Friday.
Sleep on Saturday.

After we're done, every deploy has tests behind it. Every error gets caught. Every build goes through CI/CD. You stop guessing and start shipping.

Dead Code Removal

AI writes code it never uses. Extra components, unused packages, functions nobody calls. We strip it all out so your app loads faster and your code actually makes sense.

Auth & Security Fixes

API keys in the source code. No rate limiting. Auth that works for the demo but not for real users. We lock it all down before someone else finds the holes.

Test Coverage

Your app has zero tests right now. That means every change is a coin flip. We add tests to the parts that matter so you can update your code without breaking everything.

Performance Tuning

Slow page loads. Database queries that take seconds. Memory leaks that crash the browser tab. We find what's slow and make it fast.
