The tools behind reliable infrastructure.
I focus on a core set of battle-tested technologies to deliver secure, scalable, and automated systems. Click on any card below to read my architectural engineering notes.
HashiCorp Terraform
Everything is code. I use Terraform to manage infrastructure lifecycle, enforce state consistency, and enable one-click deployments of complex cloud environments.
Docker
Creating lightweight, secure, and multi-stage Docker builds to reduce image size, speed up deployments, and eliminate the "it works on my machine" problem.
Kubernetes (K8s)
Deploying and managing self-healing, auto-scaling clusters via Amazon EKS. Utilizing Helm for package management and ArgoCD for GitOps workflows.
GitHub Actions
Building CI/CD pipelines that enforce code quality, run comprehensive test suites, and deploy to AWS automatically. Automating everything from dependency updates to infrastructure changes via Terraform PRs.
