Senior🎓
Top SchoolDongjoo L is a software engineer based in Seoul with 10 years of experience specializing in high-performance networking and AI infrastructure. He currently works on RDMA device driver patches and LLM training validation at MangoBoost, combining low-level C systems work with large-scale ML workloads. Previously he accelerated an image-generation pipeline and engineered scalable serverless features at VoyagerX, including an 800% crawler speedup achieved through cross-layer debugging and architecture changes. His background includes memory-aware caching and automatic spillover for distributed systems from a Google Summer of Code project, and practical cloud/microservice implementations from internships at EA and LG CNS. A double major in Computer Engineering and Business from Seoul National University with a Stanford summer exchange, he brings both technical depth and product-minded pragmatism. Colleagues would note his unusual mix of battlefield coordination experience and hands-on kernel-to-cloud engineering, which helps him operate effectively across teams and constraints.
