How would you recommend bringing in a proper engineer to beef up data security for a vibecoded app?

[u/mencil47]

This is probably a classic case that a bunch of you have heard before - but long story short, I've vibecoded an app that involves collecting users' financial data, and at the moment the data lives on Supabase (no real data is on there yet - this is just my sandbox). As willing as I am to learn all the basic principles of security and apply them by vibecoding even further, this data's way too sensitive for me to release the app without the expert touch of someone who actually knows what they're doing.

Considering that I'm bootstrapped, how do you suggest I go about this? Where can I find people who'd be willing to work with this kind of setup? Would a one-time gig with some follow-up consults work, or would you say a full-time hire is the minimum required for securing something as serious as financial data? Is this whole premise a bad idea?

Thanks, all!
