Good reasons to write

You have an agent to build

Multi-step reasoning, tool calling and human-in-the-loop guardrails that run reliably.

You need an MVP in two weeks

A production-ready web app with streaming UX, auth, a database and payments.

Your AI needs your data

Retrieval-augmented generation grounded in your documents, with memory across sessions.

Your AI stack keeps falling over

Fallback cascades, retry budgets and chaos testing, so a rate limit never becomes an outage.

That is enough for a scope and a timeline.
