DenmarkWhat I'm looking for
I am a senior fullstack developer from Denmark with over 17 years of experience in web development and systems integration. My expertise lies in PHP, particularly with Symfony and Laravel, and I have a strong background in cloud-based solutions and modern frontend technologies. I am passionate about creating scalable, robust, and user-friendly digital platforms that address meaningful societal and environmental challenges.
Throughout my career, I have successfully built customer-facing digital platforms, e-commerce integrations, and API-centric architectures. My recent role as an Integration Developer at Velliv involved developing and maintaining integrations on Oracle Integration Cloud, while also supporting AWS cloud migration projects. I thrive in agile environments and am committed to continuous improvement and collaboration.
My previous positions have allowed me to lead development teams, optimize cloud-hosted solutions, and enhance user experiences across various platforms. I am dedicated to leveraging technology to create impactful solutions that drive business success and improve user satisfaction.
