Me
I'm Cuong, a software engineer interested in backend systems, DevOps and cloud infrastructure. I learn by building things and writing down what happened.
I am still learning, and this notebook is one of the ways I keep track of it.
My attention usually lands on the parts of software that are easy to overlook until something goes wrong: how a service is structured, how data moves between systems, how a deployment is made repeatable, and how a small operational decision compounds over time.
I do not have a long list of accomplishments to present here. What I have is curiosity, a habit of building small things to understand them, and a growing set of notes from that process.
what I am paying attention to
Backend fundamentals, containers and deployment workflows, cloud infrastructure, and the everyday craft of making software reliable. I am most comfortable learning when I can run the thing, break it, and try again.
why this notebook exists
Writing forces me to notice what I actually understood and what I only skimmed. The study notes hold the technical trail. Moments hold the ordinary days. Trips hold the places I went to look around. None of it is meant to be polished into a finished story; it is a record of the work in progress.
