Summary
👤
Senior🎓
Top SchoolMarco Blumendorf is a Director of Software Engineering and full-stack technologist based in Berlin with 8 years of professional experience leading product-focused engineering teams across media, IoT, smart buildings and sustainability startups. He blends hands-on development (React, Node.js, GraphQL, cloud platforms) with strategic leadership—building MVPs, scaling remote teams, and setting up infrastructure and processes as interim CTO for multiple ventures. A founder and active connector in the sustainability scene (co-founder/Vice President of GreenBuzz Berlin e.V.), he mentors founders on tech, funding and recruiting while aiming to leave the world better than he found it. Marco’s background spans both research and industry—PhD-level computer science training and early HCI work through TU Berlin inform his product-first, human-centered approach to engineering. Unusually, he alternates between shipping production-grade apps and organizing community networks, making him as comfortable writing code as convening cross-sector sustainability conversations.
