At Coupang Play, I own and build backend services and internal web applications for a streaming platform, supporting content operations and playback across web, mobile, and Smart TV clients. I built and operate Next.js CMS applications for live event scheduling and control.
I launched a traffic management system with backend routing, service health monitoring, and operational dashboards, reducing playback buffering by 15%+. I also led the migration of 120K+ content assets to an AWS-based architecture, improving measured video quality by 20%+ at the same bitrate.
At Grip, I designed and built an in-house video processing platform for a short-form content product, and developed backend systems for a live-commerce platform using Python, GPU-accelerated processing, and cloud infrastructure. At 4DReplay, I developed C/C++ backend services for interactive multi-angle sports experiences and led a WebAssembly web application POC for iOS browser playback.
Earlier, at TVING, I developed JavaScript playback libraries and APIs and reduced video playback failure by 90% through client-side failover improvements. At NexPlayer, I built and customized cross-platform software SDKs for B2B customers, working with their engineering teams from technical discovery through integration and production deployment.
