Full-Stack Developer for SaaS Productionization

Looking for a full-stack developer to review and productionize an existing SaaS codebase (built largely with AI assistance) for a B2B web application. Responsibilities include reviewing and refactoring Python backend and React frontend, fixing UI issues, hardening the application for production, implementing security best practices, and setting up a deployment pipeline. Documentation of the codebase is also required. Collaboration with an existing developer using Git-based workflows is expected. An NDA must be signed before code access. Please describe your approach to reviewing an unfamiliar AI-generated codebase in your proposal.
