Summary
🤩
RockstarYu Hao Dong is a founder and backend-focused engineer with nine years of experience building censorship circumvention and networking systems, notably contributing to the widely used Geph project. He combines deep protocol-level expertise—implementing KCP congestion control, TCP tunneling, virtual TUN interfaces, key exchange, and bridge management—with practical DevOps improvements that boosted backend performance. As founder of Mel and Geph, he blends product instincts with hands-on low-level engineering across security-sensitive distributed systems. Colleagues would note his knack for turning complex networking primitives into reliable, deployable features that keep users connected under adverse conditions.
