Rockstar🎓
Top SchoolAlex Johnson is a software engineer with 13 years of experience building secure, scalable systems and a 5+ year track record at Amazon delivering production-critical services. He led design and partner integrations for a pallet delivery program that now consolidates ~75k units weekly, and previously shipped privacy-enforcing SQL compiler algorithms that withstood multiple pentests. Alex blends systems and ML work—reducing human intervention in an Amazon Go format by 44% with a fine-tuned computer vision model—while acting as a team SME on join execution and security sign-off. As an active contributor to the AWS CDK, he improved AppMesh support (TLS, outlier detection, connection pools) and strengthened IAM and testing around infrastructure code. Based in Madrid with roots in Germany and a CS degree from NC State, he pairs hands-on implementation with hiring and mentorship experience, having evaluated 20+ engineering candidates. He brings a pragmatic focus on secure, auditable delivery that moves complex B2B logistics and cloud infra features from prototype to scale.
