Situation & Challenge
A mental health startup needed a mobile platform where users could follow structured wellness programs and stay connected with professionals — without compromising privacy or stability.
- •Secure therapist–user communication channels
- •Structured wellness programs users could follow over time
- •Appointment reminders to keep engagement consistent
- •Privacy-first architecture for sensitive health data
- •Production-grade stability from day one
What I Built & Why
I architected the Flutter app with security and reliability as constraints, not afterthoughts — every integration chosen to keep user data private and the app stable under real usage.
- •Secure authentication and session handling via Firebase
- •REST API integrations for programs, messaging, and scheduling
- •Push notifications for appointment reminders and program nudges
- •Privacy-focused data handling throughout the stack
- •Clean separation of concerns to support ongoing feature delivery
Outcome
JOII shipped as a production-ready mental health app on Google Play — with secure communication, structured wellness programs, and reliable push notification delivery.
- •Secure therapist–user communication in production
- •Structured wellness programs available on mobile
- •Appointment reminders delivered via push notifications
- •Privacy-focused architecture maintained through release
