AI backend development for back-end developers

Review endpoints with contract tests instead of hand-writing them

A ready-made AI development team for your services. Hand over an API contract, a schema change, or a bug report, and approve the spec. You review a pull request with contract tests, a rehearsed migration, or a failing test that now passes.

Contract first

Implement API endpoints from your OpenAPI contract

Give the agents your OpenAPI contract. They compare it with the current service, implement what is missing in your existing codebase and write contract tests that fail if the code and the contract drift apart. You approve the spec first and review the pull request at the end.

The rest of the backlog

Assign migrations, fixes, and updates to agents

Each task runs in its own sandbox and comes back as a pull request with the available test results, review findings, and task cost. Your team reviews it and merges.

Frequently asked questions

What back-end work can AI backend development agents take on?

API endpoints from a contract with contract tests, data migrations rehearsed on a copy, bugs reproduced with a failing test, and dependency updates. Each task comes back as a tested pull request.

How do agents follow our API standards?

Write your API, logging, and error-handling rules once as skills. Every agent follows them, and the Reviewer checks each agent-built pull request against them.

Where do agents run database migrations?

Agents write the migration and its rollback and rehearse both on a copy in an isolated sandbox. Your team reviews the pull request and decides when to merge.

Can BoldCreate update our dependencies?

Yes. Agents bump a library, fix what breaks, and run your suite in the sandbox, then open a pull request.
