Back to original languageAbout Benjamin
Stripe Connect Developer | Next.js / NestJS
I participated in the implementation of Stripe Connect on Trackmate, a B2B2C marketplace dedicated to motorcycle events. The project involved a multi-party payment split system, connected account management, conditional transfers, and refund mechanisms.
It is this type of problem that interests me: critical systems where the robustness of the implementation is as important as the features themselves.
Main stack: TypeScript, Next.js, React, NestJS, Node.js, Stripe Connect, PostgreSQL, Supabase, Redis, QuestDB, and Docker.
Among my achievements:
• Trackmate -> B2B2C marketplace: Stripe Connect multi-party payment, organizer/provider system, service and booking management. Platform in production with, notably, AK Racing, 4G Moto, and Passion Vitesse.
• Prokov Éditions -> NestJS API, Redis/BullMQ pipelines, Angular analytics dashboard, and automated test suite Jest (~80% coverage).
• Studio Bemi -> custom website development for restaurateurs with automated deployment.
The descriptions tend to be similar. I prefer to let Elias Ohayon, COO of Prokov Éditions, speak for me:
"The team was blown away by his integration capabilities and the speed at which he was able to take on the project, propose production-validated solutions, bring innovative technical components, and invest himself in the project.
Benjamin is a committed collaborator, very professional despite his young age, who brings a very high level of expertise to all the projects he undertakes."
