Udip Pant is a software engineer with 8 years of experience building high-performance, large-scale distributed systems and network infrastructure, now working on Netflix’s Open Connect Edge Accelerator. He has deep expertise in caches and distributed key-value stores, reverse proxies and load balancers, and transport protocols (TCP/UDP/QUIC), and has implemented QUIC server-side support and contributed to Facebook’s open-source mvfst. At Meta he led reliability and efficiency efforts across Memcache and Layer-4/Layer-7 load-balancers, designed eBPF-based socket-level multiplexing that increased UDP throughput tenfold, and developed novel stateless TCP routing and rollout mechanisms shared at SIGCOMM. He pairs hands-on systems development with DevOps and build-system contributions (folly, wangle, katran), showing comfort across data plane, control plane, and deployment tooling. Based in Madison, WI, he combines production-scale impact with a background in performance tuning and even holds multiple patents from earlier work at Amazon.
