Health-tech platform delivery with detailed architecture, documentation, and contract-first planning
TodaiHealth shows how detailed product and technical documentation can help AI-supported implementation move faster. The work included health-tech domain modeling, architecture design, API contracts, data models, and a large implementation plan built around microservices.
This project needed more than fast coding. It required a clear architecture, defined domain boundaries, API contracts, data models, and enough documentation to keep AI-supported implementation aligned with the intended design.
The work started with specifications, architecture, and product documentation. Then came contract-driven implementation, followed by stabilization through tests, integration checks, and frontend development.
The patterns that shaped this system
- 01
Specification-first delivery
- 02
Microservice decomposition
- 03
Contract-driven implementation
- 04
AI-assisted implementation under senior architecture review
What the system looks like from the outside
- 18 microservices delivered after the specification phase
- 49 OpenAPI specifications
- 615 API operations
- 652 data schemas
- 147 database tables
- 1,200+ Markdown files in the documentation
- 436,000+ lines of documentation
This project shows careful healthcare-oriented architecture, detailed documentation, contract-first planning, a microservice split, and faster AI-assisted implementation after a thorough specification phase.
This case shows that solid architecture, API planning, data modeling, and good documentation can make AI-supported implementation faster and easier to control.
Useful for founders and health-tech teams that need to validate, plan, or build a complex MVP without losing architectural discipline.

Engagements where this case applies
Sensitive implementation details are omitted from the public version. More detailed technical discussions may be possible during discovery where appropriate.
