Senior🎓
Top SchoolJérôme Smadja is a Senior Staff Frontend Engineer based in Paris with 11 years of experience building user-facing web applications and front-end platforms. He has a strong command of HTML5, modern JavaScript, CSS architectures (BEM, Sass/Less), and frameworks from Backbone to React and Angular, plus build tooling like Webpack, Gulp and Node.js. At Qonto he progressed from Staff to Senior Staff, driving frontend architecture and delivery for a fast-moving fintech product after six years of impact at BlaBlaCar. He blends hands-on implementation—templating with Handlebars, legacy migrations, and CSS workflow improvements—with team-level process improvements such as git-flow and automated task runners. Comfortable working in consultancy and product environments, he pairs pragmatic maintenance of existing codebases with incremental modernization. Colleague feedback often highlights his knack for making frontend toolchains and team workflows more efficient behind the scenes.
