Developer needed for finalizing vibe coded software

I've currently built an automatic upsell system for a specific niche. This has been built out to be a multi-tenant app that has a main centralized database on Supabase. Each user gets their own virtual machine that runs worker processes as well as browser automation for their specific accounts. Each client also gets their own dashboard to manage just their own system, which has been built out to be a Next.js and React app deployed on Vercel. The workflow is roughly as follows. I've built it out in a way where it's able to be configured with different logic and flows according to each client's preferences and softwares that they use, but this is the main gist: a daily cron job reads the client's calendar, identifies specific upsell opportunities, drafts them to the client's dashboard. The client then looks at their dashboard and hits an Approve button, which sends out the upsell message to the guest. An AI then waits for the guest's response and classifies the upsell response as a yes, no, or unclear. If it's a yes, another message is automatically then sent to the people who actually fulfill that offer behind the scenes, asking them to see if they are able to fulfill the upsell for the specific time offered. An AI then polls their response and classifies it as a yes, no, or unclear. If it's a yes, it then sends a message back to the guest with the payment link. The core flow is working pretty much as intended in the current state. I just need a developer to make sure that the code is finalized in a production-grade way in terms of security flaws, bugs that are still present, etc. This is a completely vibe coded app, so it is 90% there, but the last 10% needs a developer to get it to production. As I actually deploy this to clients and have specific workflow alterations that vary per client, I will need to have someone look over that code as well. This is an opportunity for an ongoing role. Would love loom proposals if possible, I'm looking to hop on a call before moving forward with anyone specifically.
