Rockstar🎓
Top SchoolDavid Newell is a senior software engineer with 14 years of experience building robust systems across e-commerce, finance, and defense, and a long track record of shipping production code from front-end UIs to backend services. Comfortable in a wide range of languages and paradigms—JavaScript, Ruby, Scala, F#, and recently Elixir—he combines practical engineering with process improvements like continuous deployment and agile coaching. At Google he worked on large-scale systems, and earlier roles show leadership in API design, device-graph visualizations, and performance-focused redesigns. An active open-source contributor, he significantly upgraded the dagrejs graph libraries by migrating them to TypeScript and refactoring core graph algorithms, improving maintainability and test coverage. Based in Zurich, he pairs deep technical curiosity (coding LEGO robots as a child) with a habit of improving team practices and developer experience. Colleagues rely on him for thoughtful refactors that make complex algorithms and systems easier to reason about and maintain.
