Summary
🤩
Rockstar🎓
Top SchoolPravin Shelar is a seasoned software engineer with 14 years of deep systems and networking experience, currently at Databricks in Sunnyvale. He is an upstream Linux kernel maintainer for the Open vSwitch module and has driven kernel and userspace dataplane work for projects like Open vSwitch and Magma, including adding GTP-U, IPFIX, and segmentation offload support. His expertise spans network virtualization, SDN, VxLAN/Geneve/STT, DPDK, containers, KVM and NUMA-aware distributed systems, with strong C, Java, Python and Bash skills. At Facebook he helped design a 5G UPF and eBPF dataplane, and at Oracle and VMware he delivered cloud networking features (ACLs, NAT, load balancing) and DPDK datapaths. Known for pragmatic refactors and kernel compatibility fixes, he blends low-level packet-processing know-how with production-grade cloud networking.
