About this gig
You built fast with Cursor, Bolt,Lovable, or v0. Now you're not sure what's actually running in production. I'll tell you exactly.
I've shipped 9 production apps and audited fintech codebases to full OWASP compliance. I don't run a linter and call it a review. I read your code the way an attacker would.
What I've caught in real codebases:
- Auth tokens exposed in client-side bundles
- Unprotected server actions in Next.js App Router
- Missing rate limiting, wide open to brute force
- Hardcoded API keys sitting in git history
- N+1 queries that collapse under real traffic
These don't show up in your console. They show up in your incident report.
WHAT YOU GET:
- OWASP Top 10 security audit
- Performance review bundle size, re-renders, slow queries
- Every issue ranked: Critical / High / Medium / Low
- The exact fix for each one
- Full report (PDF or Markdown) in 24 hours
I SPECIALIZE IN:
- React & Next.js (App Router, SSR, API routes)
- AI-generated code (Cursor, Bolt, Lovable, v0)
- Auth flows (JWT, NextAuth, OAuth)
- PostgreSQL, MongoDB, Supabase, Prisma.
Want the issues fixed, not just found? I'll implement the fixes for you just pick the Standard or Premium package.
Launching soon?

I build AI-powered web apps and automation systems that actually work in production.
9+ apps shipped across SaaS, fintech, and e-commerce. Real results: 99.86% ML accuracy, 98+ Lighthouse scores, 100% OWASP security .
What I build:
→ AI automation workflows (n8n, Make, Zapier + custom agents)
→ Full stack SaaS apps (Next.js, Supabase, OpenAI API)
→ Vibe-coded app rescue (Lovable, Cursor, Bolt — fixed fast)
→ API integrations (Stripe, auth, third-party services)
I ship clean, production-grade code not prototypes. Message me with your problem and I'll tell you exactly how to solve it.

FAQ
How detailed is the report?
Very. You get every issue ranked Critical / High / Medium / Low, a plain-English explanation of why each one matters, and the exact fix for it not vague "consider improving this" notes. It covers the OWASP Top 10 plus performance (bundle size, re-renders, slow queries), delivered as PDF or Markdow
Do you fix the issues too?
Both — your choice. The Basic package is the audit + report. If you want the issues actually fixed, the Standard and Premium packages include me implementing and re-testing the fixes myself, so you get a working, secured app back, not just a to-do list.
Can you review AI-generated code?
That's my specialty. AI builders ship fast but leave behind exposed keys, weak auth, and unprotected routes that don't show up until production. I read that code the way an attacker would and catch what the console won't.
What if my repo is large?
No problem. Send me your GitHub repo or app link (Lovable, Bolt, and Replit all give you a shareable link). For larger codebases I'll focus the audit on the highest-risk areas first auth, server actions, API routes, and data access. Message me before ordering and I'll scope it with you.
Do I get the fixed code back?
With the Standard and Premium packages, yes I implement the fixes directly and hand back clean, working code with full ownership. With the Basic audit package you get the report and exact fixes to apply yourself (or upgrade anytime and I'll do them for you).
I'm launching soon / I inherited this codebase. Can you work fast?
Yes. The Basic audit is delivered in 24 hours so you know exactly where you stand before launch. If you need fixes implemented urgently, message me and I'll confirm the fastest realistic turnaround for your project.
