My name is Ricardson, also known online as r1w1s1.
I work with Linux, infrastructure, and DevOps. My focus is on building and maintaining reliable systems with an emphasis on simplicity, observability, and long-term stability.
Most of my experience involves Slackware and CentOS/Ubuntu Linux, Kubernetes and OpenShift, cloud infrastructure (AWS and GCP), and operating distributed systems such as PostgreSQL and Cassandra.
I am an active SlackBuilds.org contributor and strongly value the UNIX philosophy: plain text, shell scripts, small tools, and predictable systems.
This site is intentionally simple: plain HTML, no JavaScript, no analytics. It exists primarily as a personal archive of notes, guides, and references.
