Full-Stack Developer (Part-time)
Evolvo Tech
Two products. Health 1000 is a hospital management system sold to a hospital: I built its .NET 10 backend and lead its Flutter Windows app. The other is a four-surface service-booking ecosystem from one Clean Architecture Flutter codebase.
What I did
- Designed and built the Health 1000 backend — .NET 10, Clean Architecture, CQRS, PostgreSQL.
- Built lock-safe hospital billing, insurance, doctor-fee settlements, and FEFO inventory.
- Lead developer of the Health 1000 Flutter Windows app used by ten staff roles.
- Built the consumer, provider, web, and Windows apps of the booking ecosystem from one codebase.
Evolvo Tech builds software for service businesses and healthcare. My work there spans two products: a Flutter booking ecosystem, and Health 1000, where I work across the whole system.
Health 1000 — a hospital management system
Health 1000 runs a hospital’s patients, wards, clinics, pharmacy, labs, inventory, and accounting. It is sold to a hospital and in active development. I designed and built its ASP.NET Core (.NET 10) backend — Clean Architecture, CQRS, PostgreSQL, SignalR, Quartz, and a transactional outbox — and I am the lead developer of the Flutter Windows app that ten staff roles use every day.
The hardest part was money. Charges flow in automatically from every clinical event, payments are protected by serializable transactions and row locks, and doctor fees split and settle themselves. See the Health 1000 case study for the full technical detail.
A multi-surface booking ecosystem
My first Evolvo product is a service-booking platform across four surfaces — consumer mobile, provider mobile, a web dashboard, and a Windows operations app — from one Clean Architecture Flutter codebase on Supabase, with about 75% of the code shared. See the booking ecosystem case study.
