Freelance Multi-Tenant SaaS Programmer: Data Isolation, Custom Domains, RBAC & Billing

Building a B2B SaaS platform for enterprise customers requires strict tenant data isolation, fine-grained Role-Based Access Control (RBAC), white-label custom domains, and usage-based or seat-based billing.

As a Senior Freelance Multi-Tenant SaaS Programmer, I help founders and engineering leaders architect secure multi-tenant platforms across PostgreSQL (Row-Level Security & schema isolation), Google Cloud Datastore namespaces, AWS Cognito, and Django/Next.js. Hire Aldian Fazrihady on Upwork.
