You vibed it.
We'll ship it.

Your AI-built app works on localhost. We make it work in the real world — secure, scalable, and production-grade. In days, not months.

AI builds the prototype.
We build the production system.

Vibe coding gets you to functional software in hours. But it often misses the "invisible" engineering that makes an app safe and scalable.

Security Gaps

Hardcoded API keys, lack of proper auth checks, and exposed sensitive data are common in AI-generated code.

Scaling Walls

Prototypes often fail when hitting real traffic levels. We implement auto-scaling and database optimization.

Technical Debt

Untested, unmaintainable code that "works for now" but becomes impossible to upgrade in a few months.

Bridging the production gap.

We specialize in taking AI-assisted projects and applying rigorous engineering standards.

Code Review & Audit

A manual line-by-line review of your project by a senior engineer to identify security risks and technical debt.

Security Hardening

Implementing proper encryption, secure secret management, and protecting against common vulnerabilities (OWASP Top 10).

Cloud Infrastructure

Setting up professional hosting (AWS/GCP/Azure) with Infrastructure as Code (Terraform) and proper networking.

CI/CD Pipelines

Automated testing and deployment workflows so you can ship updates safely and reliably with one click.

Monitoring & Alerts

Full observability setup (Sentry, Datadog, Prometheus) so you know about errors before your users do.

Compliance Prep

Ensuring your infrastructure and data handling meets standards for ISO 27001, SOC2, or GDPR requirements.

The "Production-Ready" Checklist

Can your vibe-coded app answer "Yes" to all of these? If not, you're at risk.

Secrets Management

Are your API keys and DB credentials stored in a secure vault, or hardcoded in .env files?

Authorisation Checks

Can a logged-in user see another user's data by simply changing an ID in the URL?

Automated Backups

If your database corrupted right now, do you have an automated recovery point from < 24 hours ago?

Observability

Will you know your app is down before your users start tweeting about it?

Rate Limiting

Is your login endpoint protected against brute-force attacks and script bots?

Deployment Safety

Can you roll back a broken update to the previous working version in under 60 seconds?

Frequently asked questions.

Vibe coding is the emerging practice of building applications using AI tools (like Cursor, Bolt.new, or Replit Agent) where the developer describes intent in natural language rather than writing all the code themselves. It's incredibly fast for prototyping but often results in security and architectural gaps that need professional engineering to fix.

Current AI models are trained on the "average" of the internet's code, which often includes bad practices. While they are great at writing features, they often fail at systemic security (like proper auth chains) and infrastructure (like terraform or auto-scaling groups) that require deep architectural context.

We primarily work with AWS, GCP, Azure, and Cloudflare. We also help users move from "easy" but expensive platforms like Heroku or Vercel to more cost-effective and scalable dedicated cloud infrastructure.

No. We operate on a fixed-price model. You keep 100% of your company and 100% of the IP we help you harden. We are engineers-for-hire, not co-founders.
