I build and automate the path from a commit to a running service: pipelines in Jenkins and GitHub Actions, infrastructure as code with Terraform, containers on Kubernetes (EKS), and the monitoring that says when something breaks. Most of that work sits on AWS, and I am extending it into MLOps and AIOps.
Everything below is public and reproducible: each repository documents its architecture, how to run it, and where its ideas came from.
- Working on serverless and self-healing systems, and end-to-end MLOps pipelines
- Learning advanced Kubernetes and Terraform
- Open to collaboration on cloud, CI/CD, ML pipeline and automation projects
