Running multiple products in a single codebase only works when boundaries are clear.
At Job4Online, we split the platform into focused apps: Employer, Seeker, Admin, and Casual. Each app owns its UI routes and role-specific workflows, but shares platform packages for database access, schemas, utilities, and UI primitives.
What made this work
- Shared contracts, isolated features: app logic stays local, shared packages stay generic.
- Consistent auth flows: sign-in, SSO, onboarding, and account security patterns are aligned across apps.
- Reusable infrastructure: upload, RPC, and webhook patterns are standardized.
- Independent product velocity: teams can ship app-specific features without breaking other surfaces.
Practical outcome
This structure reduced duplicate code, improved release confidence, and allowed us to evolve each app’s roadmap without constant cross-app refactors.
