Professional Summary

Staff Privacy Engineer & Architect with 20+ years of enterprise engineering and a decade embedding privacy-by-design into global platforms. Architected Kimberly-Clark’s North America DSAR automation platform from the ground up — submission portals, admin workflows, backend APIs, automated deletion pipelines, and integrations with third parties — ensuring on-time CCPA compliance. Earlier, designed and hardened K-C’s SSOLS authentication system, pioneering modern privacy and security practices years before GDPR/CCPA. Known for turning regulatory requirements into scalable, automated solutions that protect consumers, reduce risk, and save millions.

I also maintain a technical blog (justingengo.com) where I publish hands-on privacy and security experiments, including TLS hardening, compliance automation, and privacy engineering best practices.
