Senior🎓
Top SchoolHendrik W is a Freelance Senior Full-Stack Engineer with 14 years of experience building scalable web applications, data pipelines, and analytics systems across JavaScript, Ruby, and Python stacks. He has led engineering teams and shipped high-traffic platforms (e.g., a shoppable-content system reaching 20M monthly users) while also transitioning ETL workloads and modernizing deployments with Docker, GCP/AWS, and Ansible. Comfortable across frontend frameworks (Vue.js, React), backend services (Flask, Rails), and real-time WebSocket architectures, he favors simple, effective solutions that scale. A strong quantitative background—B.Sc. with top marks and research on recommender systems—drives his pragmatic approach to data-driven features and optimizations. Based in Brunswick, Germany, he balances long-term freelance product work with teaching experience, bringing both hands-on implementation and mentoring strengths to client projects.
