Overview
SiKLINIK is an integrated healthcare information system for a local clinic. It connects patient registration, doctor diagnosis records, pharmacy preparation, and prescription pickup over a local area network (LAN).
What the system handles
- Unified server architecture. A C# desktop client at the registration and cashier desk talks to a Laravel web system through one server architecture.
- Structured medical records. Patient history, diagnoses, and prescriptions stay in one consistent record, so clinic staff can move through the workflow without re-entering the same data.
- Pharmacy stock control. Inventory calculations follow the prescriptions being processed, which reduces stock differences and speeds up the preparation process.
Challenge
The clinic had thousands of patient records. Searching those records from the examination client caused noticeable lag. The fix was a local cache. Each client loads patient data when the application opens, and every create, update, or delete is streamed to the client through a real-time WebSocket update. The client and server stay in sync without re-fetching the full list.
The same WebSocket channel keeps the doctor queue live. New examinations, updates, deletions, and completed visits appear immediately without manual refreshes.
Stack
Laravel, MySQL, .NET Windows Forms, and Refit.
