Your UI looks great. But v0 gave you the interface, not the infrastructure. We take v0 projects and build the backend, the integrations, and the engineering that makes them real products.
v0 generates stunning React components. But there's no database, no auth, no API layer. The UI is a shell waiting for real logic.
Every component manages its own state. Nothing is shared, nothing persists. The moment you need data to flow between pages, everything breaks.
Users can't log in. There are no roles, no permissions, no session management. The app works for demos, not for real users.
No deployment pipeline, no environment variables, no staging server. Getting it live means copying files and hoping for the best.
Payments, webhooks, background jobs, email workflows, third-party APIs. The real product lives in the code v0 doesn't write.
We review every component v0 produced. Identify what's solid, what needs refactoring, and what's missing entirely.
API routes, database schema, authentication, authorization. The server-side logic that turns a UI prototype into a working application.
Replace hardcoded props and mock data with actual database queries, API calls, and real-time state management.
Stripe for payments, auth providers, email services, analytics, third-party APIs. The plumbing that makes products work.
CI/CD pipelines, staging environments, monitoring, error tracking. Deploy with confidence instead of crossing your fingers.
Production deployment, performance tuning, security review. We stay through launch and make sure everything holds under real traffic.
We review your v0 components and map what exists versus what's needed. You get a clear report: what to keep, what to refactor, what to build from scratch.
We scope the backend and infrastructure work together. Fixed-price phases, clear milestones, no surprises. You know exactly what you're getting.
We work in your repository. Your v0 frontend stays intact while we build the backend, connect real data, and add integrations. Weekly demos to staging.
Performance testing, security review, monitoring setup. We deploy to production and stay for a support window to make sure everything holds.
