πŸ‘‹ Hey, I'm Rafael Cruz

πŸ’» Junior Cloud & Platform Engineer | DevOps | SRE

πŸ‡΅πŸ‡Ή Portugal β€’ πŸŽ“ Computer Engineering (IPCB - 15/20) β€’ πŸš€ Automating cloud infrastructure, platforms & resilient networks


πŸ‘¨β€πŸ’» About Me

I'm a Computer Engineering graduate from Portugal, focused on Platform Engineering, CloudOps (Azure/GCP), Infrastructure as Code (IaC), and Network Automation (NetDevOps).

I enjoy building resilient distributed systems, eliminating operational toil through active self-healing automation, and implementing automated CI/CD pipelines with zero-trust security.


Currently focusing on:
  • ☁️ Cloud Platforms: Microsoft Azure & Google Cloud (GCP)
  • πŸ—οΈ Infrastructure as Code: Azure Bicep & Terraform
  • 🐳 Containers & Orchestration: Docker & Kubernetes
  • πŸ”„ NetDevOps: Event-Driven Automation & SSoT (NetBox)
  • πŸ“Š Observability & SRE: Prometheus, Grafana, PRTG & Chaos Engineering

Automate. Measure. Break. Improve. Repeat.
Global Network Connectivity & Packet Routing

πŸš€ Featured Projects

🌐 NetDevOps Closed-Loop Active Self-Healing Platform

Enterprise Hybrid Network Auto-Remediation (In collaboration with ARTE, I.P.)

Active self-healing orchestration for hybrid corporate networks (Underlay MPLS + Overlay IPsec FortiGate VPN), reducing incident MTTR from 15-30 minutes to 4-7 seconds.

Python 3.11 β€’ n8n Orchestrator β€’ NetBox SSoT β€’ FortiOS REST API β€’ Netmiko (PEP 668) β€’ PRTG Webhooks β€’ MongoDB β€’ Docker β€’ Metabase

πŸ”₯ What I Built & Key Highlights

  • πŸ”„ Event-Driven Closed-Loop Orchestration: Autonomous detection via PRTG webhooks triggering state machines in n8n.
  • πŸ“– Single Source of Truth (SSoT): Runtime network state validation and drift prevention against NetBox IPAM/DCIM.
  • ⚑ Synchronous Remediation: Direct CMDB patch operations via FortiOS REST API with token auth and trusted host restrictions.
  • πŸ›‘οΈ Out-of-Band Fallback Engine: CLI contingency engine written in Python (Netmiko) running in isolated virtual environments under PEP 668.
  • πŸ§ͺ Chaos Engineering Audits: 24 fault-injection scenarios tested (tunnel drops, BGP flaps, API timeouts) achieving 100% automated recovery.
  • πŸ“Š Telemetry & Audit Trail: Real-time MTTR calculations in Metabase with immutable incident logs stored in MongoDB.

πŸ›‘οΈ CityGuards - Multi-Cloud Microservices & IaC Platform

Fault-Tolerant Civic Reporting SaaS with Automated Cloud Infrastructure

Modular microservices platform with strict transactional control (ACID), multi-cloud persistence, and zero-trust CI/CD automation.

πŸ› οΈ Stack

Azure App Service β€’ Azure Functions β€’ Azure Blob Storage β€’ GCP Firestore β€’ Azure Bicep (IaC) β€’ GitHub Actions (OIDC) β€’ Docker β€’ Node.js

πŸ”₯ What I Built & Key Highlights

  • ☁️ Hybrid Multi-Cloud Architecture: Azure compute layer seamlessly integrated with Google Cloud Firestore for synchronous NoSQL state.
  • πŸ—οΈ Infrastructure as Code (IaC): 100% of Azure cloud resources provisioned via modular main.bicep templates.
  • πŸ” Zero-Secret CI/CD Pipeline: GitHub Actions deployments authenticated via Azure Federated OpenID Connect (OIDC) β€” no static secrets stored.
  • πŸ“¦ Containerized Deployments: Container images built, scanned, and deployed using Azure Container Registry (ACR) and Container Instances.
  • βš™οΈ Fault Tolerance & ACID Integrity: Strict transaction controls preventing duplicate event processing and handling cloud failovers.
