Summary
👤
Senior🎓
Top SchoolHang Yin is a CTO and entrepreneur with 14 years of experience building production AI and confidential-computing platforms, having led Google ML efforts (notably halving Chinese ASR word error rate) before co-founding Phala and Bitcoin Gold. At Phala he scaled R&D from zero to a 15-person team, shipped Phala Cloud (5000+ users, $2M ARR), and built dstack, an open-source framework adopted by 20+ teams to slash confidential computing onboarding from months to a day. His deep systems and crypto chops show in sustained contributions to Substrate/Polkadot toolkits, Phala’s blockchain primitives, and adapting Equihash into Bitcoin Gold, reflecting a blend of low-level cryptography, consensus engineering, and ML productionization. Based in San Francisco, he combines product-driven leadership with hands-on back-end development and a track record of scaling cloud infrastructure to tens of thousands of servers.
