Front-end development and product integration on a SaaS platform dedicated to e-commerce operations for custom/made-to-order products.

I worked on the client web in React, Next.js, and TypeScript, with interfaces related to order management, products, stores, automations, user settings, and subscription flows. The goal was to make complex operational workflows clearer, faster to use, and more coherent in a multi-channel e-commerce environment.

I also developed the landing page experience and integrated Strapi CMS to allow marketing teams to manage content, page blocks, SEO, navigation, sales pages, and localized content without systematically relying on developers. The project also integrates multilingual logic on the landing page and client web.

A significant part of my work involved a visual customization editor based on Fabric.js. This tool allows users to manipulate elements on a canvas, manage design files, and connect the front-end experience to the back-end flows related to rendering, exporting, and order production.

I also contributed to the mobile interface with Expo / React Native, to extend the product experience on mobile around the dashboard, orders, user profile, and notifications.

This mission allowed me to work on a broad front-end scope, with a strong product dimension: web app, mobile, CMS, API integrations, i18n, and e-commerce-oriented user experience.
