Rockstar🎓
Top SchoolFabien Bernard is a Senior Backend Engineer based in Nuremberg with 12 years of hands-on experience building full-stack products and developer tooling. He has strong TypeScript and Node.js expertise—shaping SDKs, GraphQL servers, and REST client tooling—and has been part of founding and early teams (Xata) where he drove SDK generation, spreadsheet-like UIs and data-visualization features. Fabien blends backend systems design with frontend UX improvements, contributing to notable open-source projects such as Gatsby, GraphQL Yoga and restful-react, and even authored tooling to convert TypeScript types to Zod schemas. He excels at shipping pragmatic solutions across the stack, from subscription server handling and performance integrations to desktop distribution tooling around Tauri. Colleagues know him for improving developer experience and automating workflows (OpenAPI-driven component generation, codemods, CI hooks), and for tackling platform-specific edge cases like Windows pathing. His background in product-led startups and earlier CTO roles gives him a rare mix of strategic ownership and detailed implementation fluency.
