Enterprise Tailoring Management SaaS
A multi-tenant tailoring SaaS ecosystem with role-based permissions, offline sync, and PostgreSQL row-level security across customer, staff, kiosk, and admin applications.
Project Overview
The platform unifies made-to-measure operations into one SaaS product: customers place and track orders, staff manage production, kiosks capture measurements on the floor, and administrators control tenants, roles, and inventory. Each application shares a PostgreSQL-backed domain while remaining independently deployable.
My Engineering Role
Lead Flutter and backend engineer for architecture, multi-tenant data model, offline sync, Cloudflare R2 media, and production delivery across four client applications.
The Challenge
Tailoring businesses need isolated tenant data, strict role permissions, shop-floor capture that survives poor connectivity, and a consistent order lifecycle across four distinct interfaces.
The Solution
A Flutter multi-app ecosystem on Supabase and PostgreSQL with RLS, repository-based domain layers, offline-first sync, and Cloudflare R2 for measurement media and garment assets.
High-Level Architecture
- Four Flutter clients share a Clean Architecture domain while presenting role-specific workflows.
- Supabase and PostgreSQL enforce tenant isolation through row-level security.
- Cloudflare R2 stores media independently of transactional order data.
Key Features & Workflows
- Multi-tenant workspace isolation
- Role-based staff and admin permissions
- Offline-capable kiosk and staff flows
- Order and measurement lifecycle
- Cloudflare R2 media storage
Technical Challenges Overcome
- Designing RLS policies that stay correct as roles expand
- Synchronizing offline kiosk writes without duplicate orders
- Keeping four clients aligned on a single domain model
Production Results & Impact
- A production-ready multi-app SaaS architecture with tenant isolation as a first-class constraint.
- Operational workflows that continue during connectivity loss.
- A reusable Flutter + Supabase foundation for additional tenant-facing surfaces.
