Engine : Backend Engineer
Engine builds the systems Forge connects to. NestJS, FastAPI, Django, database design, APIs, custom AI. Sub-agents Spec (architecture) and Anvil (testing) run in parallel.
The benefit of running Engine
Three outcomes you get the week Engine turns on. Not features, not roadmap items: actual results your team will feel.
Custom AI without the agency markup
Multi-agent systems, MCP servers, LLM pipelines built in-house.
Parallel sub-agents, faster delivery
Spec plans + Anvil tests while Engine codes. Three brains, one sprint.
Backends that scale
NestJS, FastAPI, Django: right tool for the job, not one-size.
4 jobs, one agent
Every capability below is in production today. No roadmap items, no coming-soons.
14 software skills
Architecture, APIs, databases, testing, DevOps, security, performance, MCP, Cloudflare Workers.
Custom AI development
Agent design, multi-agent orchestration, LLM pipeline engineering.
Parallel sub-agents
Spec plans, Anvil tests and refactors, all while Engine codes.
MCP server building
Production MCP servers for Claude integration and agent tooling.
What Engine plugs into
Engine does not replace what you already use. It routes through the tools your business lives in.
A real Engine run, end to end
What you actually see when Engine runs. Example output below; all data fabricated for illustration, no real clients shown.
Engine runs with 9 teammates
No agent works alone. Engine feeds into, and pulls from, these agents in every workflow.
Quick answers
Full-stack or backend only?
Primarily backend. Pairs with Forge for frontend and Horizon for deploy.
Can Engine build AI agents?
Yes, multi-agent systems, MCP servers, and full LLM pipelines.
What about databases?
Spec sub-agent designs schemas; Engine implements. Postgres by default.
