Multi-tenant SaaS platform · Personal project
proxy-expert
I built a SaaS platform with tenant isolation, explicit security boundaries, a typed dashboard, and evaluation infrastructure.
01
The challenge
Design a reusable product foundation where tenant isolation, authentication, migrations, and quality checks are first-class rather than late additions.
02
The approach
Combined a FastAPI service, PostgreSQL row-level security, JWT authentication, Alembic migrations, and a SvelteKit dashboard with unit, integration, load, and golden-case evaluation paths.
Isolation by construction
Tenant boundaries are enforced in the data layer and exercised through integration tests instead of relying only on application conventions.
Evaluation as product infrastructure
Golden cases and regression tests make product behaviour inspectable as templates and workflows evolve.
03
The outcome
A working end-to-end platform foundation across backend, frontend, security, persistence, and evaluation concerns.
