About

I'm Ronald, a cloud engineer who treats infrastructure like software. I design AWS architectures that are secure, scalable and cost-aware, then codify them in Terraform so they're version-controlled, peer-reviewed and repeatable across environments.

I follow DevOps best practices: separate environments, automated deployments, remote state, least-privilege IAM, and observability built in. I also document every build so the next engineer can pick it up with confidence.

I like hard problems, and I like systems that stay reliable as they grow. I work best alongside a team, improving how things run day to day. I keep learning as the cloud keeps changing. If you're building something, let's talk.

Focus
AWS architecture, infrastructure as code, automation, cloud security, networking
Tools
Terraform, CloudFormation, Bash, Python, Git, among others.
