The day job. Oracle 19c with Data Guard, Transparent Data Encryption, RMAN and Enterprise Manager on Red Hat in Azure. Bash automation for application patching, and a daemon that runs a client's batch processing. Low-level designs, standards and procedures for each build.
Building automazr taught me the modern stack end to end. I moved a Next.js app off Vercel and Supabase onto a server I provision entirely from code: Fedora CoreOS with Butane and Ignition, rootless Podman quadlets, Postgres 18, and Caddy behind Cloudflare's proxy, WAF, Access and authenticated origin pulls. A separate host runs Prometheus, Loki, Alertmanager and Grafana, and alerts by email.
AI agents are part of how I work now. I use Claude Code, opencode, Pi and oh-my-pi from written specs, then review what they produce. They run sandboxed: one Nix-built container image holds all four, with capabilities dropped and only the project mounted, or a micro-VM. I run local models through Ollama and llama.cpp to learn where open models hold up at tool calling and where they don't.
