Your AI-Built App
Almost Certainly Has Security Holes

I'm a senior full-stack engineer (14+ years). I find the security holes in your vibe-coded app and fix them for you — before launch, without you hiring a developer.

AI Writes the Code.
I Make Sure It's Safe.

The security holes AI tools quietly leave behind — in almost every app

Exposed Data & Access

  • • Row-level security turned off
  • • Users can read each other's data (IDOR)
  • • No access checks on the API
  • • Private records left public

Exposed Secrets & Weak Auth

  • • API keys hardcoded in the frontend
  • • Weak or missing login checks
  • • Tokens stored unsafely
  • • Passwords in plain text

No Guardrails

  • • No input validation
  • • SQL injection openings
  • • No rate limiting (brute-force, abuse)
  • • Vulnerable dependencies

This isn't hypothetical

Veracode tested 100+ models and found 45% of AI-generated code introduces an OWASP Top 10 vulnerability. Across published vibe-code audits, a typical AI-built app ships with 8–14 security findings — disabled row-level security, leaked secrets and unverified webhooks among the most common.2

→ The code looks like it works. That's exactly why the holes go unnoticed until someone finds them for you — or against you.

Simple Process. You Launch Safely.

Here's exactly what happens — the free scan and the Sweep run start to finish by email

1

You send me your app

A link to your live app, plus access to the code — a GitHub link, a ZIP, or an invite to your Lovable/Bolt/Replit project. Takes about two minutes, and it's the only thing I need from you.

2

A senior engineer works your app, not a checklist

I go through your codebase and your live app with every tool that helps — and then do the part tools can't: separate the noise from what actually puts your users' data at risk, and stand behind that call.

3

Report — or done for you

Sweep ($349): a plain-English report with every issue and ready-to-paste fixes you apply yourself. Done-For-You (from $1,500): I make the fixes myself, with before/after proof — no developer needed. That one we scope on a 30-minute call first, so the price is a number and not a range.

4

Launch safely

You launch on a report you can trust — or a fixed app with proof each hole is closed. For fixes I work on a copy, never your live site, and nothing ships without your OK.

Find It. Fix It. Keep It Safe.

Know what you want? Buy the Sweep below and I'll start today. Want the fixes done for you? We scope that one together first.

  • ✓ Every issue found — not just the top few
  • ✓ Auth, RLS, secrets, injection & API checks
  • ✓ Written report + exact fix for each issue
  • ✓ Ready-to-paste fix prompts for Cursor/Lovable
  • ✓ 48-hour delivery · money-back guarantee
  • ✗ I don't apply the fixes for you

DONE FOR YOU

Done-For-You Fix

$1,500–3,500

Scoped to your app — you don't touch the code, I do

  • ✓ Everything in the Sweep
  • ✓ I implement every Critical & High fix myself
  • ✓ Before/after proof — the old exploit now returns 403
  • ✓ Guarantee: every Critical & High closed, or I keep working free
  • ✓ 30-min handover call
  • ✓ No developer needed on your side

We go over what your app does, what "done" means and what it costs — you get a fixed price, not a range. Your $349 Sweep credits toward the Fix.

Shipping new features after launch? Once we've worked together, I can keep watch on new releases — Ongoing Security Guard, from $300/mo (capped to a set number of releases). Ask me once your report lands.

Hi, I'm
Roman Sokolov

I'm a senior full-stack engineer based in Barcelona, with 14+ years shipping production software — React, TypeScript, Node.js and PostgreSQL. Today I build enterprise PaaS infrastructure used by 1,000+ companies and 14,000+ active users.

Here's why that matters for you: I build with the same AI tools you do — I've shipped AI-powered apps to the App Store and to production using OpenAI and Anthropic. So I know exactly where AI code looks perfect but quietly breaks: auth, data access, exposed keys, and messy API integrations. That's what I find and fix.

  • 14+ years full-stack: React, TypeScript, Node.js, PostgreSQL, Supabase
  • I ship AI-built apps myself (OpenAI & Anthropic) — so I know how they fail
  • Deep in the exact risk areas: authentication, data access, secrets & API integrations
  • Verify me: LinkedIn · Portfolio

"AI is incredible at writing code that works. My job is making sure it works safely — before your users, or an attacker, find out it doesn't."

What I Find in AI-Built Apps

The most common holes I check for — and exactly how I close them

EXPERIMENT — AGENT-BUILT SAAS

I let an AI agent build a SaaS blind. It shipped a cross-tenant leak.

I had an AI agent conceive, spec, and code a full multi-tenant SaaS end-to-end — I only checked that features worked and never reviewed the code, exactly like a vibecoder. It had login, auth, and database isolation switched on in the config. It still leaked: any signed-in account could reach another account's data, because three correct-looking pieces never added up to one real boundary.

→ I proved it with a failing test, closed it with two independent layers, and locked it in CI so a regeneration can't bring it back.

before → 4 failed  ·  after → 10 passed

Common holes I check for in every app:

Lovable + Supabase

Row-level security left off — any logged-in user can read every other user's records.

→ I turn on RLS and add policies so users only see their own data.

Bolt & Cursor frontends

Stripe or API secret keys hardcoded in client-side JavaScript, visible to anyone.

→ I rotate the key and move it server-side, out of the browser.

AI-generated APIs

IDOR + no rate limiting — IDs can be swapped to hit any account, with no abuse limits.

→ I add ownership checks and rate limits across your endpoints.

Questions? I've Got Answers

What actually happens with the free scan?

You paste your app's link and your email — that's the whole form. I take a real look at your live app by hand and email you the risks I can see from the outside, each with how serious it is, usually within one business day. You keep the findings even if you never buy anything, and I'll tell you if I found nothing — that's a real answer too.

If the free scan tells me my risks, why pay for the Sweep?

The free scan is a quick outside look — the top risks I can spot from your live app, and how serious they are. The Sweep is the full inside review: I go through your whole codebase, database rules, secrets and dependencies — where the most dangerous issues actually hide and an outside look can't reach. You get every issue found (not just the top few), each with exact fix steps and ready-to-paste prompts, in a written report you can act on or hand to anyone — backed by a money-back guarantee. Free tells you a problem exists. The Sweep gives you the complete map and how to close every hole. See exactly what I check →

My builder already runs a security scan and it says I'm fine. Isn't that enough?

That scan is genuinely useful and you were right to run it — treat it as step one. But it hands you a list; I hand you a fixed app and a person accountable for the result. Three real differences: I close the holes and prove it (before/after, not just flags); I give you a straight go / no-go verdict on launching, not a report to decode; and a scan is a snapshot — the next prompt you run can quietly reintroduce a hole it already passed. A scanner checks the list it was given. I read how your app is actually wired, which is where the dangerous bugs live. I'm not a rival to the scanner — I'm the human layer on top of it.

Which apps do you work with?

Apps built with AI tools — Lovable, Bolt, Cursor, Replit, GitHub Copilot — usually on a JS/TS + Supabase/Node stack. If you described what you wanted and the AI wrote the code, you're exactly who I help.

Do you actually fix the code, or just report?

Both — you choose. The Sweep gives you a plain-English report plus ready-to-paste fix prompts, so you (or your AI tool) can apply them yourself. With Done-For-You Fix, I implement the critical fixes myself and prove each hole is closed — no developer needed on your side.

I'm not technical. Will I understand the report?

Yes — that's the point. Findings are written for founders, ranked by how badly they can hurt you, with clear next steps. And if you'd rather not touch it at all, that's what the Done-For-You tier is for.

How do you fix my app without breaking it?

You share a live URL plus a GitHub repo (or a ZIP, or invite me to your Lovable/Bolt project). For Done-For-You fixes I always work on a copy or a separate branch — never your live site. You get the fixed code back with before/after proof, and nothing goes live until you approve it. Your code stays 100% confidential, is deleted after the job, and an NDA is available on request.

How fast, and what if I'm not happy?

The Sweep is delivered in 48 hours. It comes with a 7-day money-back guarantee — if the audit isn't worth it, I'll refund you, no questions asked. Rush delivery available on request.
