Rockstar🎓
Top SchoolKoki Yoshida is a seasoned software engineer with 11 years of experience building secure, high-performance distributed systems and payments infrastructure across startups and large tech companies. He has led engineering teams and technical integrations as a founding engineer at Liquido, scaled fraud and payment services with sub-10ms P99 latency, and contributed core network- and policy-level features to the open-source StackRox Kubernetes security platform. At Meta he worked on Wearables AI memory and product features for Ray-Ban Meta sunglasses, and now serves as an early Applied AI hire and founding engineer for Anthropic’s Tokyo office. His background blends systems research from Stanford (stateful software switches and P4 compilation) with pragmatic production engineering—often operating at the intersection of networking, security, and real-world vendor integrations. Comfortable shipping both infra and product features, he has repeatedly handled cross-border technical complexity (LATAM banking integrations, China dev teams) and open-source security tooling.
