About Sanjaykumar Jeyakumar

As a staff engineer at Zscaler, I leverage my 18+ years of experience in Linux internals, kernel, networking, and security domains to design, develop, and integrate cutting-edge solutions for cloud security. I lead the technical aspects of eBPF, XDP, and deception features, such as filtering, rate limiting, monitoring, and vxlan support, using high-performance and low-level programming techniques. My passion is to create innovative and scalable software that addresses business opportunities and challenges in the cloud computing space. I have a proven track record of delivering high-quality and secure products, such as cloud clients, virtualization, imaging, high availability, provisioning, and acceleration, using various technologies, such as netfilter, netlink sockets, systemd, cgroups, docker, and kubernetes. I also enjoy mentoring and collaborating with my team on virtualization, security, and cloud technologies.
