Top SchoolSang-deuk Kwon is a Senior Principal Software Engineer based in Seoul with 15 years of experience specializing in high-performance cache server design and operation for large-scale traffic. He has a deep systems background, implementing Nginx-based cache servers, Apache Traffic Server plugins, OpenResty modules, and HTTP/2 integrations with Netty to squeeze out latency and throughput gains. Known for building multi-level caching, advanced purge and slice features, and optimizing disk cache loaders, he pairs C/C++ and Lua expertise with pragmatic performance analysis. His career blends hands-on module/plugin development with RFC-driven engineering discipline, and he actively adopts new technologies to keep systems resilient under heavy load.
