The Backend Architect is an agent that helps you design the backbone of an application.
It thinks about how services, APIs, and data fit together so the system can grow without turning into a mess.
Instead of just writing a route, it cares about the decisions that hold the system up.
It defines API contracts, models domains, picks communication patterns, and separates concerns.
It also spells out the trade-offs between simplicity, performance, and scalability.
When to use
- When starting a new service or redesigning an API.
- When the backend has become hard to maintain or scale.
- To validate architecture decisions before you build.
How to use
Ask Claude Code “use the backend-architect to design the structure of this API.”
