Summary
🤩
Rockstar🎓
Top SchoolPeter Wagner is a Staff Infrastructure Security Developer with 12 years of experience building the unseen systems that keep developer teams productive and secure. Based in Waterloo, he has led supply-chain security initiatives at Shopify, shipping SBOM generation, indexing, and remediation tooling while prototyping CI/CD network proxies and package-registry policy layers. Earlier roles at GitHub and Apollo saw him design Dependabot’s backend, prototype GitHub Actions, and contribute to containerd/buildkit—experience that surfaces in his open-source work on dependabot-core. He blends hands-on systems engineering with product-minded design, mentoring juniors and reducing on-call and onboarding friction. A founder of cloud projects and a polyglot contributor across Go, Python, JavaScript and JVM ecosystems, he prefers building delightful infrastructure that most users never notice. An understated strength is his knack for turning operational prototypes into cost-effective, production-grade services that scale.
