I've built production-ready cloud systems through hands-on DevOps projects, including a Go service that generates custom macOS dynamic wallpapers and a Flask application for recording and analyzing weather data.

For the Dynamic Wallpaper Generator, I implemented asynchronous Redis job processing, Cloudflare R2 object storage, Prometheus and Grafana monitoring, and secure DNS and SSL lifecycle management through Cloudflare. I also engineered its delivery pipeline with Terraform on GCP, Traefik, Docker, and GitHub Actions for zero-downtime deployments.

For the Weather Diary Application, I provisioned a scalable, secure GKE environment with Terraform and automated testing, containerization, and deployment workflows with GitHub Actions and Helm. I used Kubernetes, Nginx Ingress, and PostgreSQL persistence to improve reliability and performance.

My Meteorology and Climate Science background gave me a foundation in scientific computing and data pipelines, which led me into cloud infrastructure and DevOps engineering. I'm also Kubernetes and Cloud Native Associate certified through the Linux Foundation and CNCF.
