Your AI-built app shipped fast. Now let's make sure it survives.

Aguilar Dev audits and rebuilds AI-generated codebases. I pair senior engineering judgment with AI-assisted analysis to catch what shipped-fast code usually misses.

if (req.body.role === 'admin') {
  return next()
}
db.query(`SELECT * FROM users`)

What every audit covers

Four things that determine whether an app can actually grow with the business.

Code quality

Clean, consistent, and free of the copy-paste sprawl, dead code, and inconsistent patterns that show up when an app was built across many disconnected AI sessions.

Maintainability

Can a new engineer actually work in this codebase, or does everything live in one founder's head with no documentation or consistent structure to follow.

Security

Vulnerabilities in the AI-generated code itself, plus the third-party libraries and dependencies it pulls in: auth issues, exposed secrets, injection risk, and known CVEs.

Scalability

Whether the architecture holds up past today's traffic. You get a specific answer for what breaks first once usage grows tenfold, not just a vague warning.

Test coverage & robustness

Do the tests exercise edge cases and failure paths, or just the happy path? A passing test suite that only checks the easy case gives you false confidence.

Where it usually breaks

Patterns that show up again and again in codebases built fast with AI tools.

A real developer looked at the repo and went quiet.

Every new feature seems to break two old ones.

You're not sure what's actually protecting user data, or if anything is.

Due diligence, a security review, or a new hire is coming, and you're dreading it.

It works today at 50 users. Nobody's checked what happens at 5,000.

How the engagement works

Three stages. You can stop after any one of them.

01

Codebase audit

A full pass through the repo: architecture, data handling, auth, error paths, scaling limits, and test coverage. You get a prioritized findings report at the end.

3 to 5 business days, fixed fee
02

Rework sprint

A scoped engagement to fix what the audit flagged, starting with anything that could lose you data, users, or a deal.

2 to 4 weeks, fixed scope
03

Ongoing oversight

Monthly retainer for teams still shipping fast with AI tools. I review architecture decisions and pull requests before bad patterns creep back in.

Monthly retainer

What actually gets flagged

A representative finding from a real category of issue.

3 sample findings
app/api/auth.tsseverity: high
beforeif (req.body.role === 'admin') { return next(); }
afterif (await hasRole(req.session.userId, 'admin')) { return next(); }
Authorization was trusted from client-supplied data instead of verified server-side. Anyone could grant themselves admin just by editing the request.
lib/db/users.tsseverity: medium
beforedb.query('SELECT * FROM users')
afterdb.query('SELECT id, name, email FROM users LIMIT 100 OFFSET ?', [page])
Unbounded query pulling every row and every column. Fine at 50 users, but a slow, memory-heavy problem once you hit 5,000.
.env.local (committed)severity: high
beforeSTRIPE_SECRET_KEY=sk_live_4f9a...
afterSTRIPE_SECRET_KEY=process.env.STRIPE_SECRET_KEY
A live payment key was committed directly to the repo history, visible to anyone with repo access, past or present.
These three cover the categories I check most: broken authorization, unbounded queries, and exposed secrets. I also look for missing rate limits and error handling that swallows failures instead of surfacing them.

Pricing

Why Aguilar Dev

I spent the better part of a decade working inside large, mission-critical enterprise codebases, the kind of systems where a bad deploy does not just annoy a few users. It costs real money and takes other teams down with it. That meant years of on-call rotations, incident reviews, and being the one accountable when something broke in production, not just the person who wrote the code that broke it. Aguilar Dev applies that same rigor to every AI-built codebase it touches. You are not getting a junior developer running through a checklist. You are getting someone who has actually carried the pager.

Questions

What if the audit doesn't find much?

Then you get a short report and some peace of mind. That happens, and it's a good outcome. You only move to a rework sprint if there's something actually worth fixing.

Do you need to talk to whoever built it originally?

No. I work directly from the repository. If the original builder (human or AI tool) is available for context, that helps, but it's not required.

What stacks do you cover?

Most common web stacks: JavaScript/TypeScript, Python, and the databases and cloud platforms (AWS, Azure, GCP) they typically run on. Ask if you're not sure yours fits.

Is this just for solo founders?

No. It's also a good fit for small teams or agencies that inherited an AI-built app from a client or an earlier hire and need to know what shape it's actually in.
