Ran 20 Docker apps on Google Cloud and AWS

Automated SSL/TLS certs for 100 Docker apps
Automated SSL/TLS certificate creation for 100 Docker applications, ensuring secure connections across Ubuntu Linux hosts.
Built GitHub Actions CI/CD pipelines
Built GitHub Actions CI/CD pipelines with a distroless production frontend image and multi‑environment promotion.
Cut systemd sandbox exposure on every unit
Cut systemd sandbox exposure across every unit this platform installs — a dead‑man's‑switch service from 9.6 UNSAFE to 1.5, an internet‑facing git forge from 8.3 EXPOSED to 1.5 — and added a converge‑time parser check after finding a misspelled directive silently ignored in three unit templates.
Ran containers on Podman and Quadlet
Deployed a container plane on Podman and Quadlet under systemd rather than Docker, because Docker publishes container ports above the host firewall's own rules — and gave deploys an unprivileged user with one fixed command instead of root.

If this is the work you need done, the next step is a conversation.
