At Samsung Research Institute, I built a debugging framework that synchronizes screen recordings with Android system logs to reconstruct user sessions and uncover hidden system events.
I implemented event extraction and timeline correlation for system crashes, helping identify, debug, and track underlying issues throughout the product testing cycle.
Previously at Arnowa, I modified Go alert-rule handlers in an enterprise Grafana v7.5.3 fork, adding server-side expressions for complex multi-query conditions. I also built REST APIs with Go and Node.js, containerized an internal Employee Management System using the MERN stack, and created custom visualization plugins and Chrome extensions.
I also build practical Go projects, including QueueCTL, a persistent CLI background job queue with retries and dead-job handling, and an open-source concurrent web crawler backed by MongoDB.
