React/TypeScript frontend + Supabase — architecture review and release readiness

📌 Short description:
A web application with a flexible structure is being developed: a separate frontend part with React + TypeScript, a Supabase database, support for multitenancy (subdomain logic), document flow, task management, and user data management.

I have independently assembled the project foundation, but now I am looking for a specialist who:

• will review the current implementation (architecture, codebase, session management, caching, routes, security)

• will help bring the project to an industrial level of deployment

• will propose or implement improvements for cross-domain authorization, API interaction, and data storage

• will help unify separate interface parts (subdomain/module zones) into a single system

⚙️ Technologies used:

• React 18 + TypeScript

• Vite as the builder

• React Query (TanStack) for data handling

• Tailwind CSS + ShadCN + Radix UI

• Supabase (auth, database, storage)

• react-hook-form, Zod, react-router, markdown editor

• Custom logic for multitenancy / subdomains / RLS rules in Supabase

🔍 What needs to be done:

1. Assess the current implementation (interface, authorization, request structure, caching, composition)

2. Help integrate the frontend zone (hub/workspace) into the main system

3. Configure authorization (cookie + localStorage + Supabase Auth)

4. Connect Supabase storage for files, editing markdown documents

5. Support the project during the launch phase

🧩 Important:
I am looking not just for a executor, but for a person with product thinking who will help organize, optimize, and launch the solution.

📅 Collaboration format:
Hourly or phased, with a focus on results. First, an audit and integration of key parts — then, by mutual interest, support and development.
