About Grégoire

Self-taught entrepreneur and full-stack developer, I have been creating web and mobile experiences since 2019 (ecommerce platforms, video creation tools, interactive maps, brand directories, art galleries, event apps), combining technology, marketing, and product vision. Always passionate about computing, I trained myself in parallel with my studies at ESSEC (Grande École program, graduated in 2022).

In 2022, I co-founded UNIQUE (+100K downloads), a platform that lists the best second-hand shops and allows you to buy their items online, where I was in charge of marketing, finance, and product.

On the marketing side, I am very proficient in creating automated email sequences and notifications (CustomerIO, Mixpanel), as well as technical optimization of funnels and product pages. With UNIQUE, I managed brand development, from copywriting to design, including social media management (15K Instagram followers). I also co-organized two vintage markets in the heart of Paris with the team (80 partner boutiques, +10,000 visitors).

On the development side, I am perfectly comfortable with the entire React ecosystem (React, React Native, Expo, Typescript, TailwindCSS) and I master several backend technologies (Node.js, Express, MongoDB, Firebase, Supabase). I am also trained on many tools with which I would be delighted to help you save time (CustomerIO, Posthog, Sentry, Algolia in particular). I like to work in an organized way and I am a fervent user of Notion, which I use on all my projects.

So if you are looking for a developer with a business & marketing vision, do not hesitate to write to me. I always enjoy discussing and discovering new projects ❤️‍🔥
