Adeline Lefebvre, Fullstack Software Engineer

About Me

My journey began in product and entrepreneurship, which gave me a founder's mindset: I love solving real problems and creating solutions that users actually love.

Today, I'm a Fullstack Developer specializing in React, Next.js, Node.js, and Flutter, focused on bridging technology and sustainability. From building a reforestation platform for Desert Leaves to creating an educational app about medicinal plants, I care deeply about building tech that matters.

I bring full-stack expertise with a proven track record of products in production serving real users across 6 countries. My background in product (Station F) means I don't just code: I understand business needs, prioritize impact, and execute fast.

Currently available for freelance missions across Europe: web development (React, Next.js), mobile apps (Flutter), full-stack projects (Node.js + React), and AI integration (OpenAI, Claude API).
