Summary
🤩
Rockstar🎓
Top SchoolStefan Zweifel is a seasoned full-stack engineer and Co-Founder/CTO based in Zurich with over a decade of experience building and operating web applications, CI/CD pipelines, and developer tools. He favors backend work in PHP and Laravel but frequently dives into frontend challenges with Vue.js and Tailwind, pairing pragmatic engineering with an eye for browser-specific detail. Stefan is a hands-on problem solver who has driven migrations, introduced CI/CD, and worn many hats at small teams—backend, devops, data, and design—to map complex business requirements to well-tested code. An active open-source maintainer, he created git-auto-commit, a widely adopted GitHub Action used across hundreds of thousands of projects, and maintains laravel-stats, demonstrating his focus on developer productivity. Outside work he channels the same meticulousness into cooking, baking, and cycling, and he writes about engineering topics on his website.
