Backend / Infra Engineer
I graduated in Computer Science at Pusan National University and work mainly on backend and infrastructure. I care less about just making things work and more about how a service behaves and holds up in production.
I am a researcher at PNU’s AI Convergence Education Institute, responsible for the institute’s software development. I build features and run the infrastructure for "Code Place", a production Online Judge. I handle operational issues on k3s and a vLLM-based AI tutor, and I chase problems down to the root cause, not the symptom.
Responsible for the institute’s software development. Own feature development and infrastructure for "Code Place", a production Online Judge. Lead a 3-person team, resolve operational issues on a multi-node K3s cluster, and built a local-LLM AI teaching assistant.
Practiced backend and infra with FastAPI, Redis, Spring Boot, and Docker across 230 hours.
A production Online Judge used in PNU's mandatory intro-to-programming course. Owned infra & backend on Django·Vue·Kubernetes(K3s) and built a local-LLM AI teaching assistant.
