Ghivalla Soumar

Senior Front-End Developer

I build fast, accessible interfaces for e-⁠commerce and SaaS, from Figma to production.

Open to senior front-end roles · Paris or remote

I'm a front-end developer with six years of experience on high-traffic e-commerce sites and SaaS platforms. I work mostly in React, Next.js and TypeScript, and I care about what users actually feel: speed, accessibility, and interfaces that stay solid as they grow.

For nearly four years at Beyable, I shipped personalization campaigns injected straight into the DOM of sites like Carrefour and Sisley Paris, where every millisecond and every browser counted. I also rebuilt Graph Patch, our Chrome extension for visual editing, and grew the IT-Client team from one person to four.

Since 2025, I've been freelancing on SaaS interfaces and on content sites built with Astro and Sanity, stepping into Node.js and SQL when a feature needs to ship end to end.
