About Me

I build backend systems the way I'd want to inherit them — clean, tested, and boring in the best way. Right now that means going deep on Java and Spring Boot: payment flows, security, and the kind of production detail (CI pipelines, sandbox testing, real error handling) that doesn't show up in a tutorial.
