Operator teardown4 days to a pilot-ready MVPFounder with light frontend experience

Built a client portal MVP in Lovable, then moved the risky backend work into Cursor

A service business needed a client-facing portal with onboarding, document upload, project status, and a paid premium support tier they could demo to pilot customers fast.

What shipped fast

Lovable handled the first-pass screens, onboarding, and dashboard structure shockingly fast. The team had something demoable on day one and a believable client flow by the end of the week.

What broke

The moment payments, file access, and Supabase policies mattered, the generated backend stopped being something I wanted to trust blindly. Stripe and access state were the obvious pain points.

What they would do differently

I would still start the first pass in Lovable, but I would move sensitive backend boundaries and payment state into a code-first setup earlier instead of pretending the generated backend was done.
