AI tools are great at the first 80%. These are the eight places founders tell us the last 20% goes wrong.
AI builds the path you described. Nobody handled the blank field, the double tap or the huge upload.
We test it like a stranger would and harden every edge before real users arrive.
Domains, environment variables, staging versus production, app store rules: the setup nobody mentions.
We set up proper hosting with separate staging and production, and take it live, app stores included.
Payments touch everything: sign-in, webhooks, refunds, failed cards. One missed webhook is money you never see.
We wire up payments and sign-in properly, and test every money path before you launch.
AI tools often leave API keys and database rules wide open. It's one of the most common ways these apps leak.
We audit access rules, secrets and backups, and close whatever is open.
The AI patches around what it can see, not what you built. Each new prompt is a gamble.
We add structure and tests so changes stop breaking things.
Nobody, you included, can explain how it holds together.
We read it, clean it up and document it, then hand you code you can change safely.
Usage-based AI tools bill for every retry, and a stuck loop can run up a large bill fast.
We finish it for a fixed price, so cost stops being a surprise.
It's hard to check invoices, timelines or progress you can't read.
You get working software every week and a fixed price, so you can see progress without reading code.
What usually breaks differs by tool. Each page covers the common problems and how we fix them.
Supabase tables without proper access rules · Public storage buckets · Login that only works in preview
It works in Bolt but not after deploy · Supabase left open · Half-finished refactors
Test data and real data in one place · No backups you've tested · Secrets and access
Four ways of doing the same thing · No tests on the paths that matter · Secrets in the repository
Built with v0, Windsurf, Claude Code or ChatGPT? The problems are the same. Book a call and tell us what you used.
Fixed price, agreed before any work starts.
A senior engineer reads your code and backend and writes up what blocks launch, with a fix-or-rebuild call. $149, credited to the fix.
You get one price for an agreed list of fixes. Nothing starts until you say yes, and the price only changes if you change the scope.
We work in your repository and show you progress on a real URL, so you can see what's done without reading code.
We take it live on your own domain and accounts, and leave a short document of what changed. A care plan is there if you want one.
For apps built with Lovable, Bolt, Cursor, Replit or v0 that work as a demo but aren't ready for real users.
