Rockstar🎓
Top SchoolZhuo Zhang is a team lead and seasoned software engineer with 13 years of experience building high-performance systems across blockchain, trading, and AI domains. Currently leading engineering at Scroll, he focuses on realtime verifiable computation and contributes deeply to open-source zkEVM projects—improving prover performance, circuit logic, and aggregation for projects like Scroll and privacy-scaling-explorations. Previously he founded and led engineering at Fluidex to build a PLONK-based Layer2 DEX and ran core blockchain development at IOST, showing a blend of product leadership and low-level crypto engineering. His early career spans high-frequency trading infrastructure, recommendation systems at Hulu, and speech/vision ML work that reached near state-of-the-art Mandarin speech accuracy. Comfortable shipping production systems and diving into circuit-level optimizations, he bridges research-grade cryptography with pragmatic backend delivery. Based in Chaoyang District, Beijing, he combines Tsinghua CS training with a track record of tackling hard systems problems that are both performant and auditable.
