Master Care
Frontend maintenance and bug-fixing across a live hospital ERP — clinical, billing, and inventory modules (registration, pharmacy, room and patient records, sales and purchasing) used by staff every shift.

Overview
Master Care is a hospital management ERP used by clinical and administrative staff to run day-to-day operations — patient registration and records, pharmacy and services, room and ward transactions, billing and cash vouchers, and the inventory and purchasing behind it all.
My role
I worked on the frontend as a maintenance and bug-fix engineer across the application — not on a single feature, but ranging over a broad set of modules in an already-live system. In practice that meant reading into unfamiliar parts of the codebase quickly, reproducing reported issues, and fixing them without regressing the workflows staff rely on shift after shift.
Modules I worked across
The work spanned most of the system, grouped roughly as:
- Users & permissions — user management and permission/access-control screens.
- Inventory — sales, sales returns, purchases, purchase returns, receipts, and payments.
- Clinical & front-desk transactions — registration, reservation, investigation, services and service lists, pharmacy, room transactions, cash vouchers, and patient records.
- Cross-cutting — general fixes that touched the whole app rather than any single module.
What I took away
Maintaining a live healthcare system is a different discipline from greenfield work: the bar is “don’t break what staff depend on,” and the real skill is diagnosing issues across modules you didn’t write. It made me comfortable navigating a large, unfamiliar frontend and shipping careful, targeted fixes under that constraint.
