From Prototype to Production

The problem

AI tools like Lovable, Bolt, and v0 have changed the game. In 2025, anyone can go from idea to working prototype in hours instead of months.

But that prototype is only 60-70% of the way to a real product. The last 20-30% — the part that makes software production-ready — is where things get hard. And it's where AI tools hit their limits.

What AI misses

Security

SQL injection, XSS, exposed API keys, missing input validation — vulnerabilities that AI doesn't catch but attackers will.

Performance

Works for 10 users, crashes at 1,000. No caching strategy, no lazy loading, no database indexing.

Error handling

Works in the demo, crashes in the real world. No graceful error states, no logging, no recovery paths.

Testing

Zero test coverage means every change is a gamble. No unit tests, no e2e tests, no confidence.

Deployment

No CI/CD pipeline, no staging environment, no rollback plan. "It works on my machine" isn't a deployment strategy.

Maintenance

Spaghetti code that works today but nobody can extend tomorrow. No documentation, no conventions, no path forward.

The code works — until it doesn't. And by then, your users are affected.

Why now

We're at an inflection point. The barrier to building software has dropped to near zero. That's incredible for innovation — but it creates a new challenge.

Founders and teams who "vibe coded" their MVPs are now facing the consequences: apps that can't scale, security incidents, technical debt that makes every new feature slower than the last.

The gap between "it works on my screen" and "it works for 10,000 users" has never been more relevant. This is the last mile problem. And it's exactly what we solve.

The LastMile Model

1. Audit

1-2 days. We review your codebase, architecture, and infrastructure. You get a clear picture of what's production-ready, what needs work, and what's a risk.

2. Harden

1-3 weeks. Security review, performance optimization, error handling, responsive design polish, accessibility compliance.

3. Integrate

1-2 weeks. Payments, authentication, third-party APIs, email/notifications, analytics and monitoring — the real-world connections.

4. Launch

2-3 days. CI/CD pipeline, staging + production environments, automated tests, uptime monitoring, launch runbook with rollback plan.

A launch-ready product — not a polished prototype.

What you get

Production build

Clean, documented code you fully own. No vendor lock-in, no surprises.

Design-polish kit

Design tokens, component library, spacing and typography system for consistency.

Integration map

Every API, auth flow, payment connection, and data pipeline documented.

Test suite + monitoring

Unit tests, e2e tests, uptime monitoring, error tracking dashboards.

Launch runbook

Step-by-step deployment process, rollback plan, incident response playbook.

30-day support

We stick around after launch to handle the unexpected. Because launches are unpredictable.

Why Rhyme

We're not just reviewers — we're builders. Our team has shipped production software for companies like PostNord, ATG, Zound Industries, and Fujifilm. We've been deep in the JavaScript ecosystem for over a decade.

That engineering foundation is exactly what makes us the right partner for LastMile work. We don't just use AI tools — we understand the code they generate, where it falls short, and how to fix it properly.

Our tech stack: React.js, Next.js, Node.js, TypeScript, Tailwind, GraphQL, MongoDB, PostgreSQL, Firebase, AWS, Vercel, Supabase, Prisma, React Native
