I joined a two-person startup from Reunion Island (1 PO and 1 backend developer) for 7 months to develop V1.0 of two platforms in Next.js/Tailwind/GraphQL. I led the frontend development of both platforms from A to Z as I was the only one in the team with React skills. The client platform is an e-commerce showcase (backend based on Vendure) aiming to highlight stores and products sold by Reunion Island's SMEs. The administration platform allows different vendors to create their store profiles and their various products. Based on this information, we developed a "builder" (based on a fork of react-page + implementation of a Lerna monorepo) that allows vendors to create digital catalogs in drag-and-drop mode. Vendors can subscribe to offers (payment via Stripe) to publish their catalogs and promote their products on the showcase. SEO, accessibility, and responsiveness were essential criteria for the project's success. I developed both platforms based on Figma mockups produced by a designer.

Frontend development on a SaaS application for property managers and co-owners to manage all issues related to residences and general meetings:

- Based on JIRA/LINEAR tickets written by a PO and Sketch/Figma mockups designed by a designer, development of new features.

- PR / Code review.

- Bug fixing on existing code.
