Hi, I'm SuIn, Roh
Django Backend Developer
๐ฐ๐ท Suwon, Republic of Korea
As a Backend Developer, My primary focus is on architecting scalable and maintainable backend systems. Believing that 'understanding operations makes for better code,' I actively experiment with deployment, observability, and automation in my personal homelab. This hands-on experience allows me to engineer solutions that consider operational efficiency right from the development phase.
