# AI products and agents, in production · Fael Caporali

> AI agents from idea to production: agents with human review, WhatsApp agents, RAG, agent evaluation and usage-based billing. Remote or in Belo Horizonte.

From an idea or a first prototype all the way to production: agents that work together with human review, WhatsApp agents, RAG knowledge bases, agent evaluation and usage-based billing.

- Construction-planning agents for large projects, in production: a root agent with a methodology specialist (Lean Construction, Advanced Work Packaging, PMBOK) and human review where the numbers matter ([the story](https://fael.caporali.dev/journey#previa))
- A construction planner that began as an n8n automation and became a product in the platform's plans ([the story](https://fael.caporali.dev/journey#brickup-ai))
- A multi-tenant platform of customer-service agents on WhatsApp, built for a regulated market ([the story](https://fael.caporali.dev/journey#ai))

## What I can build for you

- [From MVP to a product that scales](https://fael.caporali.dev/services/mvp-to-scalable-product.md): I turn MVPs and existing systems into software a team can maintain and grow: monorepo, multi-tenancy, CI/CD, infrastructure as code and cloud architecture.
- [Quality without slowing delivery](https://fael.caporali.dev/services/qa-and-test-automation.md): Test strategy and automation, feature flags and observability, and a QA function that stays with the team after I leave.
- [Technical leadership and team training](https://fael.caporali.dev/services/tech-leadership.md): Leading a team from the problem to the delivery: requirements, cadence and deadlines, hiring, and training people until the team runs on its own.
