Senior🎓
Top SchoolDaniel Jahnsen is a hands-on senior developer lead based in Copenhagen with 12 years of professional experience building cloud-native, full-stack and mobile solutions. He combines strong Azure/.NET microservices architecture expertise with practical mobile development (React Native, iOS) and a history of shipping CI/CD, containerized and event-driven systems across enterprise clients like Ørsted and the LEGO Group. As a longtime consultant and former founder/CEO of a software consultancy, he pairs architectural rigor (DDD, Onion/Clean architectures, Terraform/IaC) with product-minded delivery and client-facing ownership. Recent roles show a pattern of leading technical teams on complex public-sector and logistics projects while still contributing code and dev-ops work. He also maintains a habit of side projects and long-term freelance engagements, demonstrating curiosity across Ruby on Rails, frontend frameworks and native app stacks. This mix of enterprise-grade architecture, startup agility and practical mobile experience makes him effective at turning complex requirements into maintainable, scalable systems.
