ABOUT
Woojin Kim
I enjoy working through problems. When something is frustrating, I want to know why. When I see a possible fix, I want to try building it. Software lets me turn those ideas into something real quickly. That’s what got me hooked on development.
I’m studying Software Convergence at Kyung Hee University. I co-founded Raspy, shipped our product, and ran it at live sports tournaments. At Afinit, a Series E fintech company, I worked on company-wide AI development infrastructure. I also led a university festival platform used by students and pop-up pub operators. My work has included deciding what to build, not just implementing a feature list, and adapting it to how people actually use it.
Most of my work is in backend systems and infrastructure, but I’ve also built apps and developer tools when the problem called for them. I like learning unfamiliar technology and digging into what’s blocking me. I treat the problems I take on as my own. Working code isn’t the finish line; I want to know whether it’s actually useful.

Learning together
LikeLion KHU
Ran project-based sessions for beginners and experienced members to grow at their own levels. Later shifted toward system-design presentations and discussions so members could explain their design choices in their own words.
Also led the new chapter’s official website, launching project and activity records, recruitment, content management, and authentication in August 2026.
Teaching algorithms
Teach C++, Python, data structures, and algorithms according to each student’s level and goals. Students have earned KOI and USACO awards and admission to science high schools through software-focused selection.
