We’re a founder team building a quoting and booking platform for mobile catering businesses—a multi-tenant SaaS where each business manages its clients, pricing, and quotes. Our users buy access as part of our coaching academy, paying a recurring platform fee and a transaction fee for each event booked.

The core front end and workflows are complete using Lovable (React + Supabase). We need a senior engineer to take our demo to a production-ready level, focusing on backend hardening, implementing Stripe Connect payments (including subscription billing), enforcing strict multi-tenant security through Supabase, and ensuring compliance and data privacy standards. You should be able to carry out a Postgres row-level security audit for tenant isolation, work comfortably with the existing codebase, and provide input on what’s worth keeping or reworking from AI-generated code. Experience launching a multi-tenant SaaS with Stripe Connect is a must. Please share your relevant portfolio, a reference, and a brief estimate on effort for both payments and security.

Budget range:
$1,500 – 3,000 USD
