Summary
🤩
Rockstar🎓
Top SchoolYangang Gao is a Senior Software Engineer with 13 years of experience building high-performance systems, currently based in Haidian District, Beijing and working at Grab. He has strong low-level and systems expertise demonstrated by contributions to prominent open-source projects like cgminer (ASIC/FPGA mining drivers) and OpenHFT’s zero-allocation hashing (Java memory and Unsafe optimizations). His background spans large consumer tech companies including ByteDance and Qihoo 360, and he holds a Master’s in Computer Science from Xidian University. Yangang excels at hardware-software integration, cross-platform driver work, and Java performance tuning, often solving tricky compatibility issues such as big-endian support and environments without Unsafe.getByte(). Colleagues rely on him for pragmatic, performance-first solutions that bridge embedded firmware and backend infrastructure. He combines deep technical craftsmanship with a track record of shipping production-ready improvements in both C and Java ecosystems.
