One platform, every team.
Context
Several client organizations needed their own isolated, secure workspace, without running a separate deployment for each one.
The Challenge
Tenants had to be cleanly isolated with role-based permissions, while the platform stayed fast and consistent as it scaled across organizations.
Approach
I designed a multi-tenant architecture with role-based access control, real-time data and serverless cloud functions, then tuned performance with lazy loading, code splitting, caching and query optimization, which made it up to 60% faster.
Key Decisions
- 01
Multi-tenant data model
Isolated tenants with shared infrastructure from a single codebase.
- 02
Role-based access
Granular RBAC so each user sees only what they should.
- 03
Serverless functions
Cloud functions handle business logic that scales on demand.
- 04
Performance tuning
Lazy loading, code splitting, caching and query optimization for ~60% gains.
What Shipped
- Multi-tenant architecture from one codebase
- Role-based access control
- Real-time data sync
- RESTful APIs and serverless cloud functions
- ~60% performance improvement
