You built it with Bolt.
We'll make it production-ready.

Your app runs. Users are showing up. But Bolt gave you speed, not structure. We take Bolt codebases and turn them into software that scales, stays secure, and handles real-world traffic.

Sound familiar?

Bolt shipped fast. But now...

01

The full-stack scaffold is fragile

Bolt generated frontend, backend, and database in one shot. But the pieces are tightly coupled, poorly structured, and hard to change without breaking something.

02

Security was an afterthought

No input validation, no rate limiting, API keys in client-side code. The app works for demos but would fail any security review.

03

The database schema doesn't scale

Tables designed for the happy path. No indexes, no migrations, no plan for what happens when you have 10,000 users instead of 10.

04

Error handling is hope-based

When things go wrong, the app crashes silently or shows a blank screen. No error boundaries, no logging, no way to know what broke.

05

You can't add features without refactoring first

Every new feature requires touching five files. The generated code has no clear architecture, and the complexity grows faster than the product.

What we do

We work with your Bolt code.
Not against it.

01

Audit the full stack

Frontend, backend, database, deployment. We map every layer Bolt generated and identify what's solid versus what needs work.

02

Fix the foundations

Proper database schema with migrations and indexes. Clean API layer with validation. Authentication that actually works.

03

Add real error handling

Error boundaries, structured logging, alerting. When something breaks, you know about it before your users complain.

04

Harden security

Input validation, rate limiting, secrets management, CORS configuration. The security basics that protect your users and your data.

05

Build the missing features

Payments, real-time sync, background jobs, email workflows, third-party integrations. The features that turn your MVP into a product.

06

Set up for scale

CI/CD pipelines, staging environments, monitoring, performance tuning. Infrastructure that lets you ship fast without breaking things.

How it works

From Bolt prototype to production app

01

Audit

We read every file across the full stack. Map the architecture. Flag the risks. You get a written report with a clear plan: what to keep, what to fix, what to rebuild.

02

Plan

We scope the work together. Fixed-price phases, clear milestones, no open-ended retainers. You know what you are getting and when.

03

Build

We work in your repository. Weekly deploys to a staging environment you can test. Every change has a pull request, a review, and a test.

04

Harden & Ship

Performance testing, security review, monitoring setup. We deploy to production and stay for a support window to make sure everything holds.
