Hi, I’m Arthur Santos, a Senior DevOps Engineer and Site Reliability Engineer focused on building reliable, scalable cloud and hybrid infrastructure. I specialize in Azure Cloud architecture, Infrastructure as Code (Terraform/Bicep), Kubernetes orchestration, CI/CD automation, and production incident management in enterprise and financial environments. I have a proven track record of improving deployment velocity, reducing operational risk, and maintaining high-availability systems that support mission-critical workloads. My software engineering background in .NET, Python, and Angular enables me to own the full lifecycle from development through production operations. I’m open to US-based remote contracting. I enjoy collaborating with cross-functional teams, sharing DevOps best practices, and delivering pragmatic automation that boosts efficiency. I’m always looking to improve performance, reliability, and scalability, and I thrive in fast-paced, delivery-focused environments.
