Summary
🤩
Rockstar🎓
Top SchoolSong Gao is a software engineer with 12 years of experience combining a PhD-level background in data mining and security with production engineering at Google. He brings strong analytic and problem-solving skills across Matlab, Java, C/C++ and SQL, and a track record in machine learning techniques from CART and SVMs to clustering applied to vision tasks like image segmentation, retrieval, and real-time tracking. His open-source contributions span high-impact projects—implementing JSON functions in the cloud-native TiDB database and adding NAT64 support to OpenThread and its POSIX border router—demonstrating expertise in back-end systems, embedded networking, and IPv6/IPv4 translation. Based in Mountain View, he blends research rigor from his KDDM lab work with pragmatic engineering that improves databases, IoT stacks, and networking toolchains. An engineer who moves fluidly between low-level protocol work and data-driven feature design, he also has a knack for squeezing efficiency from numeric types and explain-plan improvements in large codebases.

Jul 2022 - Dec 2022
OpenThread released by Google is an open-source implementation of the Thread networking protocol
Role in this project:Back-end Developer & Embedded Systems Engineer
Back-end Developer & Embedded Systems EngineerContributions:216 reviews, 14 commits, 35 PRs in 5 months
Contributions summary:Song primarily contributed to the implementation of NAT64 functionality within the OpenThread project, focusing on IPv4 packet processing and translation. Their work involved adding new classes, updating data structures, and extending checksum capabilities to support IPv4, ICMP, and other protocols. Furthermore, they implemented CLI commands for interacting with and monitoring the NAT64 translator, including CIDR configuration, mapping inspection, and performance counters. The contributions also include improvements to the build system and tests related to NAT64.
