Technical Stack

Tools I use in production.

A practical stack built around cloud infrastructure, Kubernetes, automation, security, observability, and AI-assisted engineering.

I care less about collecting tools and more about understanding how they behave in production — how infrastructure is provisioned, secured, deployed, observed, and recovered.
