Your app has good vibes.
And a fatal flaw.
Maybe you built it with AI yourself. Maybe you hired someone who did. Now it has paying customers, and the cracks are showing: silent data leaks, no tests, a database one query from falling over. We're the engineers who turn vibe-coded products into systems that survive production.
However it got built,
it's fixable.
From funded startups to established small businesses, our clients arrive one of two ways. Neither involves being a software engineer, and neither involves a lecture about what should have been done differently.
You run the business, and you built the product.
You used Cursor, Lovable, Replit or ChatGPT and got a working product in front of paying customers. That's genuinely impressive. But now there's revenue on the line, customer data to protect, and questions you can't answer yourself: is it safe? will it hold up? what happens when it grows?
"I don't even know what I don't know about this code."We do. We translate the technical reality into plain language, then fix it. No judgment, no jargon.
You hired a vibe coder, now you need it to be real.
A freelancer or agency built it fast and cheap with AI. It demoed beautifully. Now you need it to scale with your customers, pass a security review, or stand up to investor due diligence, and you're not sure what you actually own or whether it'll get you there.
"I need an honest, vendor-neutral read on what I've got."That's the audit. A senior engineer audits the code and tells you the truth, then hardens it for production.
The last 20% is where
production actually lives.
Vibe coding is genuinely great at getting you started. It's terrible at the unglamorous engineering that keeps an app alive under real load, real users, and real attackers.
It's leaking, quietly
Secrets in the frontend, open endpoints, no rate limiting. It works in the demo because nobody's poking at it yet.
Falls over at users > 50
Queries that loop the database, no caching, no indexes. Fine for you. A timeout for everyone else.
Every change is a gamble
Zero tests means each new feature has a chance of silently breaking three old ones. Velocity goes to zero.
The LLM is the weak point
Prompt injection, hallucinated outputs treated as truth, no grounding, runaway token costs. AI features that look magic and behave randomly.
Spaghetti you can't extend
One 4,000-line file, copy-pasted logic, no boundaries. The next feature takes longer than the last every single time.
No idea when it breaks
No logging, no monitoring, no backups. You find out it's down when a customer emails you. Usually the important one.
We don't rewrite it.
We make it production-grade.
You keep the product you built and the speed it gave you. We add the engineering rigor underneath: the part the tools skipped.
Security & data isolation
We close the leaks: secret management, real auth & access control, input validation, and the information-isolation patterns we use in regulated industrial systems, applied to your app.
- auth & RBAC
- secret rotation
- pen-test pass
- data-flow audit
Performance & scale
Profiling down to the query and the frame. We've taken inference from 300 ms to 6 ms on shipped products, and the same instinct finds your bottleneck and removes it.
- query tuning
- caching
- load testing
- cost reduction
Reliability & tests
Automated tests, CI/CD, monitoring, alerting and backups, so changes stop being scary and outages stop being surprises. Built the way safety-critical fleets are.
- test suite
- CI/CD
- observability
- on-call ready
AI & LLM systems done right
RAG pipelines, grounding, prompt-injection defense, evaluation and deterministic guardrails. We build LLM systems where security and predictable behavior are core requirements, not afterthoughts.
- RAG
- guardrails
- evals
- grounding
From audit to deploy.
Audit
A Production Readiness Audit: an AI-assisted, automated scan plus senior review. You get a ranked report of every critical issue. The fee is credited toward the fix.
Prioritize
We agree on a fixed scope and a flat quote. Critical leaks first, nice-to-haves last. No open-ended hourly drift.
Fix & harden
We work in your repo, in branches, with tests. You see every change reviewed and explained. Nothing happens in a black box.
Hand back
Documented, monitored, and yours. We leave you a system you can keep building on, or we stay on retainer.
Not another tool.
Engineers who've shipped.
The work is led by people who have spent a decade owning the reliability, performance and security boundary of real production systems: in eye-tracking, autonomous vehicles, and industrial control.
Julio Chana
10+ years building software that businesses and their customers rely on every day. He has worked where mistakes are not an option: self-driving trucks, eye-tracking hardware, and AI that handles confidential data. Today he focuses on making AI-built apps secure, reliable, and ready for real customers. His work has been shown at the world's largest tech expos and featured on national TV.
PCVue Latam · AI for industrial systems
Building AI for factories and infrastructure, where data has to stay isolated and the system must behave the same way every time.
Independent · AI products for businesses
Built AI tools that turn customer emails into quotes and answer staff questions from confidential company data, without leaking it.
Tobii · Eye-tracking technology
Built the software behind consumer eye-tracking products, where speed and careful handling of personal data are everything.
Scania · Self-driving trucks
Led a team of 9+ engineers building tools for autonomous heavy trucks. Software where "it can't break" is literal.
Manomotion · Real-time computer vision
Founding engineer. Made the core product 50× faster and built software used across thousands of apps and devices.
Common questions.
What is a "vibe-coded" app?
An app built mostly with AI coding tools like Cursor, Lovable, v0, Replit or ChatGPT. These tools get you to a working demo fast, but usually skip the security, testing and architecture that real production needs.
Can you fix an app built with Cursor, Lovable, or v0?
Yes. We work inside your existing repository and harden what you already have, with no forced rewrite. We handle the common stacks: Next.js, React, Node and Python with Supabase or Postgres.
How do you find what's wrong with my app?
We start with a paid Production Readiness Audit: an AI-assisted, automated scan plus senior review that ranks every critical issue in plain language. The fee is credited toward the fix if you go ahead.
Do you work with startups in San Francisco and New York?
Yes. We work with founders and teams in San Francisco, New York and remote worldwide. Everything is done remotely, with clear, reviewed changes in your repo.
Send us the repo.
We'll tell you what's wrong.
A senior engineer, backed by automated analysis, audits your codebase and sends a ranked report of every critical issue. Fixed fee, credited toward the fix if you go ahead.
