Jojy Varghese is a systems-focused software engineer with 12 years building low-latency, high-throughput core infrastructure across cloud, networking, and embedded domains. He has architected Siri’s speech and NL runtime stacks at Apple serving thousands of requests per second with sub-150ms latency, and previously drove kernel- and network-level work at Cisco, Juniper, and Mesosphere. Skilled in C/C++, Linux kernel internals, distributed systems, and system design, he contributes to notable open-source projects such as Envoy (adding UDP and transport socket functionality) and Apache Mesos (containerizer and cgroup improvements). Based in Fremont, CA, he blends deep systems craftsmanship with practical production experience in proxying, load balancing, and real-time synchronization for AR, making him adept at turning complex low-level requirements into reliable, scalable services.
