Back to original languageAbout Léa
Product Designer & Front-end Developer specialized in SaaS | UX/UI + Next.js + Conversion Landing Pages
Thanks to my dual profile in design + development, I reduce back-and-forth between UX, UI, and code. I design fluid user experiences (UX research, wireframes, UI design) and then develop them cleanly with Next.js and modular design systems.
My approach is simple:
- Understand the real needs of the product
- Deliver testable prototypes quickly
- Develop scalable and performant interfaces
This method allows me to save my clients time, launch faster, and improve business impact from version 1.
I work on:
- Web interfaces (B2B/B2C SaaS, dashboards, business tools...)
- Mobile applications (PWA, React Native)
- Conversion-oriented landing pages (A/B testing, copy/design/CTA)
Need a hyper-operational hybrid profile to accelerate your design + front-end delivery?

Experience
- MaméeArtistic Direction | Meal Planning AppTECHMay 2026 - May 2026Lyon, FranceMamée is a meal planning application for French families, positioned between the passive inspiration of Marmiton and the closed automation of Jow. The user composes their menus, and the app calculates the rest (nutrition, budget, shopping list).I led the complete artistic direction sprint: logo, color palette, typography, illustration system, and initial applications. The goal was to build a strong visual universe that would stand out from the sector's tech/clean codes. The chosen direction: retro/artisanal, with recipe cards designed like product labels, stamps by culinary family, and cinema tickets to share a menu. Warm, appetizing, and printable (market street marketing planned in Lyon).The visual redesign of the app's UI prototype follows in a retainer: weekly planning screens, recipe card, shopping list, onboarding.
- HYPERGROWTHProduct Design + DevelopmentCONSULTING AND AUDITSMarch 2026 - Today (3 months)Bordeaux, FranceHyperGrowth is an agency specializing in acquisition and growth. I work as a product designer and developer on their digital ecosystem.Main project completed: migration of the existing website from Webflow to Next.js to regain control over performance, optimization, and scalability.

- Sam DéménageWeb Migration + SEOLOGISTICS AND SUPPLY CHAINFebruary 2026 - March 2026 (1 month)Bordeaux, FranceMigration of the website for a moving company in Bordeaux to a Next.js stack with Sanity CMS for the client's editorial autonomy. The existing site had an SEO strategy already in place and a local positioning that absolutely needed to be preserved: the main challenge was to faithfully reproduce the structure identically without losing accumulated SEO juice, while transitioning to a modern and performant stack.I managed the entire technical SEO work related to the migration: mapping of existing URLs, 22 301 redirects, sitemap redesign, JSON-LD MovingCompany markup on all pages, structured FAQs, and 17 geographic area pages to cover Bordeaux and its surroundings. In parallel, I integrated a multi-step quote calculator to improve conversion and provide visitors with an immediate estimate without having to pick up the phone.From design to launch, ensuring the transition was invisible to search engines.
