A selection of things I’ve built — across security, systems, and applied AI.
A proof-of-concept that runs the same prompt down two paths at once — straight into the model, and through a guardrail — and streams both pipelines live, so the difference between "unprotected" and "defended" is something you can watch rather than argue about. (In progress)
Departments, labs, and clubs each run their own web server, and almost nobody wants to think about TLS. Building a portal and a one-command installer that issue and renew publicly trusted Let's Encrypt certificates on their own — with central visibility over every server. (In progress)
A 3-year, ~USD 130M institution-wide program at KAIST — I analyzed and systematized the university's most rule-dense domain (curriculum, course registration, classes, graduation) from design through deployment. Recognized with a Special Commendation.
A web service that auto-extracts highlight clips from Twitch VODs by fusing NLP on chat logs with CNN-based facial-expression analysis.
Prototyped low-latency, deterministic V2X messaging on a Linux real-time kernel and benchmarked latency for safety-critical vehicle communication.
Research on preventing double-spending in private blockchains — published at IEEE and filed as a patent.
