Back to original languageAbout Alexandre
Senior Front-End Developer specializing in Javascript and TypeScript with over 7 years of experience, I have built products from scratch for ambitious startups (NFT marketplace with $50M valuation or a platform with 2 million members).
An entrepreneur at heart, I founded and managed Eden Store (physical and digital convenience store at festivals), where I simultaneously led business strategy, multidisciplinary team management, and the technical development of a click & collect platform.
This dual tech/business background allows me to go beyond code: I understand product challenges, I structure architecture to support growth, and I know how to deliver quickly and effectively in demanding environments.
Available for React-Native, ReactJS, or NextJS missions, or for leadership positions where autonomy, product vision, and technical rigor make the difference.
