About Me

I’m zS1m, a software engineer interested in web engineering, systems, and long-term project design. I enjoy working on real-world projects, where constraints, trade-offs, and imperfect decisions are part of everyday engineering.

About This Site

This blog collects engineering notes from projects I build and maintain over time. Rather than step-by-step tutorials, most articles focus on production issues, architectural decisions, and lessons learned during development.

Why "Contrails"

Contrails are traces left behind by movement — subtle, temporary, but meaningful. In a similar way, this site serves as a record of ideas, experiments, and engineering paths taken along the way.
