Senior🎓
Top SchoolRoberto Ruiz is a software engineer and UX designer with 11 years of experience, currently shaping product and research-led interfaces at PATCH Handwerk from Siegen, Germany. He blends front-end engineering expertise—Next.js, TypeScript, Redux, RxJS and performance optimization—with a human-centered approach from his MSc in Human-Computer Interaction. Roberto has led cross-functional teams, delivered large LightningJS and React projects, and reduced Next.js load times by a third through targeted optimizations. He is also an educator and mentor, having taught hundreds of students and run workshops that scaled junior developers to staff level. Comfortable running end-to-end projects, he pairs deployment and backend experience (Strapi, Vercel, cloud functions) with a knack for turning user research into measurable product improvements. Outside product work he writes and teaches code—making tools and showing others how to build them.
