Staff Engineer at @madeiramadeirabr. I build the platform and the measurement layer the rest of engineering runs on.
- Developer productivity — DORA and flow metrics pulled from Jira and Git, collected and served as a product instead of a quarterly spreadsheet.
- Platform engineering — containerized collectors and services on AWS/ECS, CI/CD, and the paved road other teams ship on.
- Observability and quality — Grafana, Prometheus/Loki, SonarQube: making regressions visible before they become an incident.
- Agentic tooling — Claude Code skills, MCP servers and agent orchestration, pointed at real engineering workflows rather than demos.
Most of my work lives in private repositories. The contribution graph below is the shape of it — the content stays where it belongs.
