Multi-tenant elder-care SaaS
A complete care ecosystem: patient app, caregiver app, tenant and super-admin consoles, and the API — with multi-tenant RBAC, a booking-to-medication care loop, geo-validated service areas, and GST-aware invoicing.

What I built
- Built white-label patient and caregiver Flutter apps sharing a single codebase, configured per tenant via build flavors.
- Engineered the multi-tenant RBAC system: orgs, care centers, and staff each with scoped permissions — a wrong role getting the wrong data was never acceptable in an elder-care context.
- Built the full care loop: booking, caregiver assignment, roster management, medication tracking, and attendance — all connected.
- Implemented GST-aware billing, multi-payment invoicing, and branded PDF receipts with correct tax breakdowns.
- Added geo-validated service areas and in-app notifications (BullMQ) so caregivers and patients only see what is relevant to their region.
