Hi! My full name is Yeongseok Lim but you can call me Eddie :) I was born in South Korea, continued my education in the U.S. starting in high school, and studied Computer Science at the University of Wisconsin-Madison. I'm interested in backend systems and AI, and this site is where I document what I build. I also enjoy connecting with people from different fields and talking about the latest tech. I'm currently working as an AX Engineer at LG CNS in Seoul. Let's stay connected!
As a financial software engineer at LG CNS, I'm working on a core banking modernization project for a Singapore-based bank. I focus on fit-gap analysis, cross-border and internal payment flows, SWIFT integration, and functional requirements for the new payments platform.
Collaboration project between LikeLion Madison Chapter and MoDoc AI, a health-tech startup. I built a LangGraph-based AI pipeline that turns child medical text content into short videos.
ClearSplit is an iOS app I developed to solve expense splitting problems with my roommate during college. I especially put a lot of effort into building the backend structure for this app. This is one of my favorite projects, please visit my GitHub!
As the AI era has increased the value of computing resources, I worked with two LikeLion teammates to build a system that orchestrates multiple devices on the same network and trains an image classification model in a distributed way. We implemented it with a master-worker architecture and also built a frontend for monitoring results in real time.
In this project, I implemented a filesystem, shell, and scheduler on top of the xv6 operating system to learn core OS concepts. It was my first experience with C, but it gave me a solid foundation in OS knowledge that every developer needs.
I'm passionate about open source. While browsing Pyrefly's issue board, I found an interesting issue, got it assigned, and had my PR merged. This was my first open source contribution, and I continue to explore other projects today.
