M.S. in Electrical Engineering, National Cheng Kung University (DBSE Lab). Focused on infrastructure, reliability, and platform engineering, with a strong backend and developer-tooling streak.
I like owning systems end-to-end: designing them, operating them in production, and handing them over in a state someone else can run.
- Personal infrastructure — self-hosted homelab of 11 Docker services on a Raspberry Pi, 20+ months in continuous operation: 3-tier ELK observability stack, encrypted Cloudflare R2 backups, and a GCP reverse-tunnel bastion for secure access behind NAT.
- Linux kernel coursework (fibdrv, ksort, lab0-c, proxylab) — C systems work from Jim Huang's (jserv) NCKU kernel courses: a Fibonacci character-device driver (
kmalloc/kfree,file_operations,ioctl), an in-kernel sorting module, and a multi-threaded HTTP proxy. - LDAP SSO sandbox (ldap-sso) — Docker-based testing environment for LDAP single sign-on, built to de-risk a production identity migration (OpenLDAP + Keycloak, ~50 accounts federated with zero password resets).
