Rockstar🎓
Top SchoolJoan Sanuy is a freelance product and web app developer with 12 years of experience designing and building user-focused web products from research to production. He blends front-end expertise (React, Redux, SASS) with backend skills (Node, Koa, MySQL) and a strong emphasis on UX, knowledge management and tagging systems. As a founder of multiple startups and remote collaborator with teams like OccamzRazor (Stanford), he excels at translating user interviews and field research into fast prototypes and feature-driven roadmaps. Comfortable across management, support and engineering, he uses Scrum and Kanban to keep product delivery aligned with real user needs. Multilingual and based in Barcelona, he documents his process publicly via a technical blog and open repositories, reflecting a disciplined, research-informed approach to product development. An underappreciated strength is his consistent focus on information architecture—breaking complex domains into manageable, reusable pieces for long-term product learning.
