Rafael Friederick

Backend engineer @ A3S Tecnologia · based in Salvador, Brazil.

Currently building unnamed-lab — a self-hosted Kubernetes platform on bare-metal Proxmox. Go services, ArgoCD GitOps, observability stack (Prometheus / Grafana / Loki / Tempo), CloudNativePG, Kong.

Open source

Contributor to CNCF projects — merged upstream:

  • kubernetes/minikube#22960 — only warn against the virtualbox driver when the user explicitly asks for it, instead of when minikube auto-selects it
  • kubernetes/minikube#22992 — update cri-dockerd to v0.4.3 in the none-driver integration script
  • argoproj/argo-cd#27769 — include resource context in failed normalization logs, so operators can tell which resource failed

In review: kubernetes/minikube#23037 — move per-machine sockets out of MINIKUBE_HOME so AF_UNIX paths fit in sockaddr_un.sun_path.

Stack I operate in production

  • Go 1.25+ · Gin · pgx (no ORM) · hexagonal architecture
  • TypeScript / Node · NestJS · Next.js · TypeORM · CQRS
  • Kubernetes (k3s) · ArgoCD · cert-manager · MetalLB · Harbor
  • PostgreSQL 18 · Redis · RabbitMQ
  • Observability · OpenTelemetry · Prometheus · Grafana · Loki · Tempo
  • IaC · Terraform · Ansible

Writing

Bilingual tutorials on distributed systems & observability — tracing (PT for now, EN coming).
