Senior🎓
Top SchoolDennis Westphal is an experienced full-stack developer and IT consultant based in Berlin with a decade of hands-on experience designing and delivering web applications, product management, and software architecture. He founded and ran FilesMania for nearly two decades, blending development, hosting, and training services, and later scaled conversion-driven CMS solutions at ebuero AG that cut landing-page production time by 95% and raised conversion rates by 20%. Since 2016 he’s combined freelance consulting with product leadership at Coredna, helping teams ship features while shaping technical strategy. His background spans PHP, Angular, Java web technologies and modern PHP7-era architectures, with practical expertise in A/B testing and growth-focused experimentation. Trained at Technische Universität Berlin (M.Sc.) and with a B.Sc. in Wirtschaftsinformatik, he brings both academic rigor and entrepreneurial grit. Less obvious: he pairs product ownership skills with developer-first tooling and processes, making him effective at translating marketing and business goals into maintainable engineering outcomes.
