8+health institutions
50K+patient records
2,000+patient transactions a week
~75%shorter patient waiting times
1,000+inventory items tracked by the module I owned
~33%higher retention from the feedback system
The problem
Clinics ran patient records, appointments, billing and stock on paper and disconnected tools.
What I built
A Rails monolith with patient intake, scheduling, records, provider dashboards and subscription billing, backed by PostgreSQL, Redis and Sidekiq on Heroku.
Highlights
- Owned the stock and inventory module, roughly halving expiry and quantity issues.
- Built an anonymous patient feedback app with analytics.
- ACID-safe workflows for records, billing and audit trails.
- Redis caching that cut page loads by about 75%.
