Freshman Software Engineering Student @ Ajou University
I build things at the intersection of ML theory, systems, and real-world deployment.
I'm a 1st-year Software Engineering student who cares deeply about understanding why algorithms work, not just running them. My work spans ML research tools, physics simulation, NLP, and practical web services β all grounded in solid mathematical and engineering principles.
- π¬ Core interests: Deep Learning Theory Β· Physics-Informed ML Β· Systems & OS Fundamentals
- π₯ Applied goals: Medical AI (diagnostic imaging) Β· Industrial AI (process optimization)
- π Philosophy: derive before you import; optimize before you scale; question before you trust
