You built an app with AI (Claude Code, Cursor, Lovable, Bolt, whatever) and it works. But before you let real users and real money in, there's a nagging feeling: is the payment flow actually safe, is anything exposed, will it hold up in production?
That's what I review.
13 years building and shipping production software, including apps with live Stripe payment flows, in regulated industries (banking, insurance, healthcare) where getting security wrong was not an option. I build AI-assisted apps myself, so I know exactly where AI-generated code tends to cut corners.
What I check (launch-critical only):
* **Payments:** Stripe/checkout integration, webhook validation, amount/price tampering, refund, and subscription edge cases
* **Security:** exposed secrets and keys, auth and access control, injection, insecure direct object references
* **Data privacy:** what gets stored, what gets logged, what leaks to the client
* **Production safety:** error handling, rate limiting, the things that break on day one with real traffic
What you get: a written report, findings ranked by severity, each with a concrete fix. Not a rebuild, not a redesign. A focused pre-launch review you can act on (or hand to anyone).
Stacks I cover: React/Next.js, Node, Python/FastAPI, Supabase/Firebase, Stripe.
**Rate:** flat **$450** for a standard single-app review, 2-3 day turnaround. Bigger or multi-service apps are quoted up front. Optional follow-up fixes at **$90/hr** if you want me to implement, but the report is yours either way.
DM me a short description of your app and stack, and I'll tell you honestly whether a review is even worth it for you.
