Rockstar🎓
Top SchoolWatson Sato is a Senior Software Engineer based in Berlin with 12 years of experience specializing in security-focused backend engineering and automation. At Red Hat he has advanced OpenSCAP and compliance-as-code projects, fixing subtle policy engine bugs, closing resource leaks, and improving security configuration profiles used by widely adopted tooling. His background includes leading development teams at Kryptus and hands-on research experience from CTI Renato Archer, giving him a blend of applied security engineering and team leadership. Watson’s open-source contributions show attention to detail—resolving Jenkins validation issues, renaming PCI-DSS profiles for correctness, and addressing kernel-module and systemd control options to harden systems. He excels at turning security requirements into auditable, production-ready solutions and enjoys tackling tricky static-analysis findings that others might overlook. Fluent in building secure, maintainable tooling, he brings both implementation depth and a pragmatic mindset to compliance automation.
