Raymond Julin is a seasoned full-stack technologist and co-founder with 17+ years delivering web products, tooling, and developer experience across startups and scale-stage companies from Bergen, Norway. He blends deep appreciation for UX with low-level implementation craftsmanship, primarily using JS/TS to build impactful, production-ready systems—from booking platforms and headless commerce tooling to real-time in-store displays. As a hands-on leader he has founded and led engineering teams, driven technical architecture (microservices, Kubernetes, GCP) and shipped customer-focused features as CTO and technical lead. An active open-source contributor, he has improved front-end projects like a jQuery timepicker and Home Assistant thermostat UI, often focusing on developer experience, code quality and responsive behavior. Equally comfortable in product strategy meetings and debugging runtime issues, he also spends time hacking home automation and balancing work with family life.
