Top SchoolKittipong Ruangsiriluk is a Principal Software Engineer with 14 years of experience building and securing high-scale authentication and web services, currently leading full-stack development for Norton authentication supporting over 200 million accounts. He is a Java-focused engineer who pairs hands-on backend implementation (Spring, Tomcat) with scripting and testing in Python, plus deep familiarity with Linux systems and embedded C/C++ work. His expertise spans authentication protocols (CAS, OIDC/OpenID Connect, SAML2), modern password hashing, and practical security practices such as threat modeling, fuzz testing, and automated security assessments. Known for mentoring engineers and providing cross-team guidance, he also documents APIs and product designs to keep systems auditable and maintainable. Beyond standard duties, he experiments with security tooling and builds lightweight utilities—such as client-side encoders/decoders for SAML2/JWT—to prototype real-world interoperability solutions. Based in San Gabriel, CA, he blends legacy-system fluency with modern identity engineering to improve user experience and security at scale.
