E-Health PWA
An end-to-end Progressive Web App (PWA) designed for a leading hospital group to streamline healthcare access — from digital doctor appointments and vaccination booking to electronic medical records and patient loyalty rewards.

Manual WhatsApp booking became a self-service app that patients actually use.
User growth
OneBunda users grew almost 70% from January to March 2023, after launch.
Registered patients
Customers registered on the OneBunda platform by March 2023.
Frictionless healthcare access
Manual appointment bookings shifted into a self-service, always-on digital booking channel.

Overview
OneBunda is the patient app of Bunda Group — RS Bunda hospitals, Morula IVF and Diagnos labs. It replaces a confusing eHealth experience with one place to register, book, pay and follow up on care.
The problem
Patient access to hospital services was heavily fragmented and reliant on manual channels like WhatsApp booking, leading to high drop-offs and operational inefficiencies.
Business pain points
Lacked integrated core features (doctor booking, vaccination scheduling, loyalty rewards) and had no direct sync with the hospital’s internal Health Information System (HIS).
Patient experience pain points
Booking appointments manually was confusing and time-consuming, while patient health records and rewards were untrackable online.
Who it’s for
Patients & families
Seeking quick, seamless online appointment booking, digital health tracking and rewards management across mobile and desktop devices.
Hospital care teams & staff
Requiring real-time synchronization between digital bookings and the internal hospital system (HIS) to streamline patient intake and schedule management.
What I designed
Digital doctor & vaccine booking
A streamlined 3-step scheduling flow for in-person consultations, teleconsultations and vaccination packages.
Integrated loyalty program
A point-earning and reward redemption ecosystem integrated directly into patient consultation activities to boost retention.
Health records & medical history
A central dashboard allowing patients to track consultation histories, prescriptions and lab results digitally.
Seamless HIS integration UI
System workflows aligned with backend hospital management systems to ensure real-time schedule syncing.
How I approached it
01 — Research & discovery
Mapped patient journeys, identified manual booking bottlenecks, and aligned business goals with hospital IT requirements.
02 — Ideation & user flow
Designed clear, frictionless booking and registration flows, eliminating unnecessary steps to improve completion rates.
03 — Wireframing to interactive prototyping
Built low-fidelity structures up to high-fidelity, component-driven PWA prototypes using a clean design system.
04 — Usability testing & iteration
Validated key task completion scenarios with real patients to refine edge cases prior to developer handoff.
