Senior🎓
Top SchoolRaymond Jelierse is a Staff Engineer with 11 years of experience building and operating full-stack web and mobile products, currently working at Bird after a multi-year tenure at Contextmapp. He has led major re-architecture efforts—rewriting legacy dashboards in Laravel and rebuilding mobile research apps with Ionic/Angular—while owning APIs, infrastructure, and deployments. Comfortable across backend, frontend and DevOps, he has architected RESTful services, OAuth-protected APIs, and multi-instance web apps using technologies like Symfony, MongoDB and ElasticSearch. Raymond combines hands-on coding with team leadership and coaching experience from startups and academy settings, and he has run his own hosting business to deliver end-to-end client solutions. Based in North Holland, he pairs an MSc in Design for Interaction with a practical engineering background, bringing a user-centered mindset to scalable systems. A detail not obvious from titles: he has repeatedly modernized brittle legacy stacks into maintainable, upgradeable platforms that accelerate feature delivery.
