Top SchoolJustin Paulin is a production engineering leader with 12 years of hands-on experience building and optimizing large-scale infrastructure at Meta, LinkedIn, and Shopify. Fluent in Python, PHP, Ruby, JavaScript and multiple systems languages, he combines deep full-stack chops with production-first reliability work—reducing capacity needs and slashing build times through targeted tooling and config refactors. He has repeatedly shipped end-to-end systems (databases, CLIs, React UIs) that bridge developer tooling and runtime operations, and has led migrations, on-call improvements, and capacity optimization for Core Data. Comfortable across Linux, FreeBSD, containers, and cloud platforms, he pairs pragmatic systems engineering with a history of measurable efficiency gains. A Waterloo CE graduate, he maintains a public portfolio and GitHub that surface a long-standing curiosity for practical hacks—from embedded ARM projects to infra automation—reflecting both breadth and operational focus.
