DevOps Engineer com base sólida em desenvolvimento. Trabalho com servidores Linux, containerização (Docker, Kubernetes), proxy reverso (Nginx), VPN (WireGuard) e automação de deploy.

Mantenho sistemas multi-tenant em produção, infra de agentes de IA conversacionais e integrações com APIs externas. Quando precisa, também boto a mão no código (Node, TypeScript, .NET, Python) pra resolver o problema de ponta a ponta.

DevOps Engineer with a solid development background. I work with Linux servers, containerization (Docker, Kubernetes), reverse proxy (Nginx), VPN (WireGuard) and deployment automation.

I keep multi-tenant systems running in production, including infrastructure for conversational AI agents and integrations with external APIs. When needed, I also write code (Node, TypeScript, .NET, Python) to solve problems end-to-end.

• k3s-daily-cleanup - daily cleanup for terminated pods, containerd images and old logs on K3s
• linux-vps-cleanup-daily - daily cleanup routine for Linux VPS running Docker and/or K3s, never touches active workloads
• docker-frequent-cleanup - every-30-minutes cleanup for hosts that build a lot of Docker images
• fix-k3s-docker-bridge - one-shot fix for the silent K3s + Docker bridge issue (kube-router FORWARD DROP)
• puppeteer-grafana-screenshot - automated Grafana dashboard screenshot via Puppeteer for reports
