Circuits
Each service drawn as its own sub-circuit, with engineering notes alongside.
R1
Web applications
- Browser-based tools for customers or staff
- Accessible, responsive interfaces
- Designed with users, iterated in small releases
Note: Pairs with U1 when the app needs data from other systems.
U1
Integrations & APIs
- Connecting existing systems so data moves without retyping
- Designing and documenting APIs
- Replacing brittle manual exports
Note: Usually the junction everything else plugs into.
C1
Data & cloud
- Data models, pipelines and reporting foundations
- Cloud hosting set-up and cost awareness
- Backups and recovery planned up front
Note: Stores charge: what the other components rely on.
K1
Modernisation
- Reworking older software step by step
- Adding tests around existing behaviour first
- Keeping the lights on during change
Note: A relay that switches load from old to new gradually.
