Summary
👤
Senior🎓
Top SchoolJonathan Levaillant is a Front-End Integrator and Web Designer with over a decade of experience crafting responsive, modular HTML/CSS interfaces and driving visual revamps for major sites. Starting from a back-end and networking education, he combined formal multimedia graphic training with hands-on roles at Toluna and Groupe Pratique to evolve into a specialist in atomic design, OOCSS, BEM and fluid layouts. He has led design-to-production workflows, internal quality and training efforts, and routinely applies advanced CSS techniques (3D transforms, flexbox, SVG/canvas) to elevate UI polish. Currently at JoliCode, he brings a rare mix of build discipline and visual sensibility, often translating design systems into reusable, accessible templates and email-compatible markup. Colleagues know him for rigorous autonomy, continuous tech watch, and a knack for turning complex design requirements into maintainable front-end architecture.
