Model and optimise the data layer
Schemas, indexes and caching so the system holds up in production with no latency surprises.
Testing and deployment
Stepping into someone else's code and leaving it better: tests, CI/CD and observability.

Good contract design and data modeling, with judgment on consistency and performance.
Testing and deployment

AI Engineer
When the product integrates LLMs or agents, backend and AI Engineer come in together.
Salesforce Developer
In enterprise accounts, the backend integrates with platforms like Salesforce via API.
