Senior🎓
Top SchoolSagar Balani is a Senior Software Engineer with a decade of hands-on experience building networking software for ASICs and cloud-scale platforms, currently at AWS after leadership roles at Intel. He began at Barefoot Networks where he owned a portable Kernel Packet Driver and helped bring the first Tofino-based ASIC support into SONiC, contributing low-level drivers and platform integrations in a widely used open-source SONiC buildimage. His work spans P4-programmable dataplanes, SDK/SAI implementation, L2/L3 forwarding, ACLs, QoS, and platform bring-up—bridging silicon, SDKs, and OS integration. Known for tackling cross-layer problems, he combines systems-level rigor with practical deployment experience across startups and large enterprises. Based in San Jose, he pairs an MS in Networking with a track record of shipping production networking features and upstreaming platform support.
