Available to hire
Hi, I’m Fred Klein. I’m a full-stack software developer with 30 years of experience, focused on frontend technologies and UI/UX, passionate about building scalable SaaS products and elegant architectures. I enjoy turning complex requirements into intuitive, robust software and leading teams to deliver value.
I’ve built two SaaS products. I’m comfortable across the stack: frontend (Angular, React, TypeScript), backend (Node.js, MongoDB), cloud (AWS, Google Cloud, Azure), and iOS native development. Worked in a multilingual European tech scene, I speak French, English and German fluently and have spent nine years in Zürich, which informs my approach to global product design.
