Summary
👤
Senior🎓
Top SchoolSeokju Yun is a seasoned backend engineer with 12 years of experience building real-time, high-throughput services—especially for games—across startups and large studios. He has led server teams at Nexon and implemented production systems at Smilegate and Sendbird, solving hard problems like large-scale time-series sharding, real-time WebSocket delivery, and GameLift integration for million-DAU titles. His work mixes hands-on systems coding (Python, Node.js, Go) with operational ownership on AWS, including rolling updates and high-availability architectures. Notably, he contributed bug fixes upstream to gopacket and built Beats plugins to capture encrypted game packets for ML pipelines, enabling analytics without modifying game servers. Now based in Gyeonggi, South Korea, he brings a pragmatic blend of performance optimization, cross-team collaboration, and product-focused engineering to real-time backend challenges.
