- I’m Hojae Lee, passionate about algorithms, real-time systems, and blockchain.
- 4th-year Computer Engineering student at Hongik University.
- I enjoy building products end-to-end — from system design to on-chain logic.
- My favorite animal is the pelican 🐥
- I build first and optimize later. (Fail fast, learn faster.)
