About

Background and approach

I am a software engineer focused on JavaScript and cloud systems. I have several years of experience building and maintaining production applications.

I try to keep systems simple and predictable for users and teams. When building them, I often question existing patterns and look for simpler ways to solve the problem.

I prefer clear code and strong systems over trends. I build software that can grow without becoming hard to understand.
