Stress-Test My App for Scale & Failure

Good logs save you at 2am. Bad ones leak data and tell you nothing. Get this right.

Most AI-built apps turn into spaghetti. Get the structure right up front.

Protect user data properly — before a leak makes the decision for you.

Before you let real users in: the checklist that catches what vibecoding skips.

A landing page that converts, generated clean and ready to tweak.

That app you built pulls in hundreds of packages you've never read. Find the risky ones.

Get your data model right before you build on top of it.

Login and signup without losing a weekend to auth docs.

Clean up messy AI-generated code safely — one small change at a time.

Before you ship AI-generated code, have it checked by something that won't sugarcoat it.

The scariest bug: one user seeing another's data. Check your auth before someone else does.

The #1 vibecoding mistake: API keys sitting in your code or git history. Hunt them down.

The audit nobody does after vibecoding. Find what'll break or get exploited before users do.

Inherited code you didn't write? Get the map before you touch anything.

The standard checklist real engineers use. Run your app through it in plain English.

Stuck on an error you don't understand? This gets you unstuck without the lecture.

The prompt that makes Cursor add a feature cleanly instead of rewriting half your app.

The first prompt to paste into Lovable or v0 so you get something real, not a toy.

Before you build anything with AI, get the spec right. This writes the PRD for you.

Your query's slow and the EXPLAIN output is gibberish. Paste it — get what's actually happening, the bottleneck, and the index or rewrite that fixes it.

It works but it's slow. Paste it — get where the real bottleneck is, the optimized version, and whether the speed-up is even worth the complexity.

A mock interviewer that runs you through a real system design round, interrupts like the real thing, and scores you at the end. Brutal on purpose.

See a UI you like? Describe it and rebuild it instead of starting from a blank page.

Dropped into unfamiliar code? Paste it. Get the map — what it does, how it flows, and where the bodies are buried — before you touch a thing.
