AI SaaS Bug Fix Needed

We already built a SaaS application that uses Azure OpenAI to detect and fix bugs in code. The system includes a web interface, backend API, SQLite database, and Stripe integration for subscriptions. Most of the app is already in place, but there’s a bug in the flow that’s breaking everything. The issue seems to be in the tracking/first step of the bug detection process, and because of that, the full system isn’t working properly. We now need an experienced developer to help fix some bugs and stabilize the existing MVP. The main focus is debugging, improving reliability, and ensuring all features (AI responses, UI flow, and Stripe payments) work correctly. Looking for someone who has experience with full-stack SaaS apps and API integrations, especially with OpenAI/Azure OpenAI and Stripe.
