⚡ Technical Due Diligence • The Last 20% Architecture

We Take Your 80% AI-Built Codebase Across the Finish Line.

You vibe-coded a prototype that kinda works. But auth is fragile, state leaks memory, and the layout looks like generic AI boilerplate. We diagnose breaking points, harden the architecture, and engineer a custom, high-converting product you're proud to show investors.
