Rockstar🎓
Top SchoolKuai Wei is a software leader and CEO based in New Zealand with eight years of industry experience and a deep technical foundation from advanced studies in computer science. He blends hands-on systems engineering—contributing JVM performance and AArch64 improvements to the flagship openjdk project—with startup and product leadership, having built fraud-detection SaaS as CTO and now leading 3E Software. His background spans full-stack SaaS architecture, DevSecOps and CI automation, and low-level performance work including JIT, register allocation and memory-barrier optimisations. Notably, he has migrated platform-specific components for Alibaba’s Dragonwell JDK and improved build automation for complex cross-platform Java distributions. Kuai pairs research-grade rigor from PhD-level training with pragmatic product delivery, making him comfortable moving between kernel-scale performance problems and customer-facing cloud services.
