Yannick Loriot is a seasoned software engineer with 15 years of experience, currently working on WhatsApp at Meta after contributing across Horizon and Workplace projects. He blends mobile-first craftsmanship in iOS and Swift with full‑stack skills in Node.js and React, shipping performance and reliability improvements at scale. As a former CTO and co-founder, he brings product-minded engineering, CI/DevOps and team processes to bear on fast-moving projects. A prolific open-source contributor, his Swift libraries (color manipulation, custom UI controls, QR readers and interactive transitions) emphasize polish, usability and test coverage. He is fluent in both hands-on UI/UX work and backend reliability fixes (e.g., Socket.IO client fixes), and often pairs visual design sensibilities with low-level Core Graphics and animation expertise. Based in the UK and trained in software engineering and applied math, he’s known for curiosity, autonomy and a knack for turning prototypes into production-grade components.
