Rockstar🎓
Top SchoolRaymond Cohen is a Senior Staff Engineer with 14 years of experience building scalable front-end architectures and developer workflows, currently shaping Square’s Foundation Web Platform from Georgia. He authored Square Dashboard’s microfrontend architecture to integrate React into a legacy Ember.js monolith, enabling independent deploys and faster development cycles adopted by a dozen+ teams. Raymond has driven migrations to modern bundlers (Embroider/Webpack) and led product-facing efforts like a Restaurants POS free tier and Paperless Post’s Flyer editor, balancing platform-level design with customer impact. A long-time Ember contributor and QA-focused open-source collaborator, he has contributed meaningful tests and feature fixes to projects such as ember.js and QUnit. He combines pragmatic engineering (deploy-from-S3, previewable static assets) with hands-on implementation, often bridging legacy stacks and modern JavaScript tooling. Trained at Carnegie Mellon, he’s known for shipping practical solutions that reduce operational friction while improving user-facing performance.
