Overview
Keklinik is a full-stack medical platform designed to digitize and streamline the operations of clinics across Indonesia. The platform covers everything from patient registration and appointment scheduling to electronic health records (EHR) and billing — delivered across both web and mobile interfaces.
The Goals
- Digitize clinical operations, shifting clinics from error-prone paper records to a secure digital SaaS.
- Simplify patient scheduling, reducing appointment wait times and double-bookings.
- Build a compliant Electronic Health Records (EHR) database accessible by doctors, nurses, and admins.
The Idea
“The idea was born from observing how Indonesian clinics still relied heavily on paper-based systems, leading to lost records, scheduling conflicts, and poor patient experiences. The goal was to create an affordable, user-friendly SaaS platform that could be adopted by small and medium-sized clinics without extensive technical onboarding.”

The Process
Visited clinics to observe patient flows and identify key bottlenecks in paper record tracking.
Designed relational schema for clinics, users, and appointments to prevent data duplication.
Built the backend API first, followed by concurrent web and mobile frontend development.
Conducted load testing on database locks and deployed the platform onto cloud servers.
Added automated reminders via WhatsApp, significantly reducing no-show rates.
Key Highlights
- Multi-role access control (Admin, Doctor, Nurse, Patient)
- Real-time appointment status updates
- Offline-capable mobile app with sync-on-connect
- Electronic Health Records with audit trail
- Automated appointment reminder via WhatsApp & SMS
The Result
The platform went live, successfully digitizing several clinic operations across Indonesia. It reduced patient registration times by 50%, cut appointment no-shows by 30% through automated WhatsApp notifications, and successfully managed thousands of electronic health records with secure auditing.
Challenges & Solutions
One of the biggest challenges was handling concurrent appointment bookings and ensuring data consistency across web and mobile clients. We implemented optimistic locking on the database layer and a queue-based notification system to handle high traffic reliably.
