Yuki Takei is a seasoned technology leader and CTO with 12+ years building backend, infrastructure, and data-driven systems, currently steering product and engineering at iDEAKITT. He is the original creator of Soto, a widely used Swift AWS SDK that works across Linux, macOS and iOS, and has authored multiple Swift server frameworks (Hexaville, Slimane), reflecting deep expertise in server-side Swift and cross-platform tooling. Yuki blends hands-on engineering—contributions to AWS SDK shape definitions and Linux compatibility—with product leadership, having developed the user research platform Tanaka-san. A frequent speaker, writer, and open-source maintainer, he pairs practical startup experience and freelance versatility with ongoing doctoral-level research interests in causal inference at JAIST. Notably, his work bridges low-level systems (libuv-based frameworks) and cloud APIs, enabling Swift to thrive beyond iOS.
