Top SchoolMarvin Schirrmacher is a security engineer with 11 years of practical experience securing cloud and payment systems, currently focused on protecting high-volume payments at paymenttools. He has deep hands-on expertise across threat modeling, security design reviews, cryptography and PCI requirements, with production experience in Java, Kotlin, Go, GCP and Kubernetes.
