SaaS platform engineering for multi-tenant products with accounts, subscriptions, billing, security and room to scale.
About SaaS Platform Engineering
A software-as-a-service product serves many customers from one platform. That brings specific engineering needs: tenant separation, subscriptions and billing, role-based access, usage tracking and reliable operations.
Getting the foundations right early is cheaper than retrofitting them. We design the tenant model, permissions and data boundaries first, then build features on top.
