## What I can build for you

Closed-scope projects, contracts and consulting. Every offer below comes from work I've already delivered.

### [AI products and agents, in production](https://fael.caporali.dev/services/ai-agents.md)

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))

### [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.

- Five MVPs built with Lovable brought into one monorepo, with row-level security and Terraform on GCP ([the story](https://fael.caporali.dev/journey#bid))
- A warehouse system, from triage to shipping, in production ([the story](https://fael.caporali.dev/journey#bid))
- A live shopping platform moved from a single server to ECS, with blue-green deployments and infrastructure as code ([the story](https://fael.caporali.dev/journey#devops))

### [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.

- Open defects down from about 300 to under 100, together with engineering ([the story](https://fael.caporali.dev/journey#qa))
- Monitoring and proactive alerts that catch failures before customers have to report them ([the story](https://fael.caporali.dev/journey#qa))

### [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.

- Designed the hiring process and coordinated a team of five developers ([the story](https://fael.caporali.dev/journey#brickup-lead))
- Trained the team in new quality practices, and the QA who took over my role ([the story](https://fael.caporali.dev/journey#qa))
- Mentored a junior developer and handed over with the team trained and operating procedures in place ([the story](https://fael.caporali.dev/journey#ai))
- Led an international project in English, setting cadence and deadlines between the client and the developers ([the story](https://fael.caporali.dev/journey#techlead))

- Belo Horizonte, Brazil
- Remote for Brazil and abroad, or hybrid in BH
- Portuguese and English
- Closed-scope projects, contracts or consulting

## A bit of what I've delivered

### AI customer service on WhatsApp, in a regulated market

Tech Lead and Full-Stack Engineer. [The story](https://fael.caporali.dev/journey#ai)

- Designed and built a multi-tenant platform of AI agents, with RAG, an agent evaluation tool and token-based billing, and mapped every requirement of the sector's regulation to the code.
- Set up CI/CD with unit, integration and E2E tests, led a team of five and handed over with the first clients live and the team trained.

### A construction-tech platform

QA Manager and Tech Lead. [The story](https://fael.caporali.dev/journey#qa)

- Led the construction-planning agents, from an n8n automation to products still in production.

### Device trade-in and asset management

- Brought five Lovable-built MVPs into a single React/TypeScript monorepo, with multi-tenancy through PostgreSQL row-level security, CI/CD and Terraform on GCP.

- Led engineering across three products, in English, between the client, the international team and the Brazilian developers.
