Summary
👤
Senior🎓
Top SchoolShota Sawada is a software engineer based in Tokyo with nine years of experience specializing in backend identity and authorization infrastructure, primarily implemented in Go. He led the migration from a Django-based identity system to an OpenID Connect–certified Go/Ory stack at an autonomous driving company, contributing multiple PRs to Ory projects (Hydra, Kratos) and presenting at Ory Summit. His work spans design and operation of OAuth2/OIDC authorization servers, gRPC/REST APIs, client SDKs, 2FA (TOTP, WebAuthn), and large-scale migrations that cut latency and eliminated downtime. Shota favors designing cross-cutting, reliable platforms with clear boundaries that multiple teams can depend on, and he has driven company-wide practices like blue/green deployments and staged feature releases. He also has hands-on SRE and migration experience from earlier roles—moving services to ECS, codifying IaC, and improving observability with Datadog tracing. Notably, his contributions helped harden widely used open-source projects relied on by organizations at web scale, reflecting both product and security-minded engineering.
