I will check your lovable or supabase app for security holes and launch it
Leandre J.
About this gig
Apps built with Lovable, Bolt or Replit on Supabase often go live with holes their owners never see: database tables anyone can read, secret keys sent to the browser, prices that can be changed before checkout. Before real users or payments arrive, I check your app for these and close them.
What I check:
- Database rules (RLS) on every table: who can read, change or delete what
- Keys and secrets that should never reach the browser
- Sign-in settings, password reset and email confirmation
- Payments: webhooks and prices that could be faked from the browser
- File storage that anyone could list or download
What you get:
- A plain-English report: each problem, how serious it is, and the fix
- On the higher packages, the fixes made and tested, and your app live on your own domain
- Your accounts stay yours, and my access is removed at the end
I build and run my own live apps on Supabase and Vercel with sign-in, billing and user data, so I check yours the way I check mine.

I fix, finish and launch web apps, including ones built with Lovable, Bolt, Replit or Base44. I also automate Google Sheets and Excel work, and build AI chatbots that answer your customers' questions. I build and run my own live products on Next.js, Supabase and Vercel: a shop till that keeps selling offline, a rent receipts app for landlords, a bank statement reader that checks every line to the cent, and a contract reader that shows the clause behind every date. Every order gets the same care: tested before delivery, with a plain note on what changed. Based in Guyana, on US Eastern time.

FAQ
Do I need to pay for hosting?
Only on the launch package. Most small apps run on the free plans of Vercel, Netlify and Supabase, and if yours needs a paid plan, I tell you the cost first.
Can I still edit my app in Lovable or Bolt afterwards?
Yes. Your builder keeps syncing with GitHub, and each change you publish there goes live on your domain automatically.
Is this a hacking test?
No. With your permission I review your own app's code, database rules and settings: the checks a careful developer makes before launch. Nothing is attacked, and your data stays in your accounts.
What access do you need?
Read access to your code (a GitHub invite or a zip) and to your Supabase project. For fixes and launch I need edit access, which you remove the moment I deliver. I never need your passwords.
What if you find problems that are not about security?
I list them in the report with a short note on each. Fixing them is not part of this gig, but I can send a custom offer, or you can order my app fix gig.
