Back to original languageAbout Marco
Senior backend developer specialized in Node.js and TypeScript, I support startups, scale-ups, and large corporations in the design, development, and evolution of their web applications.
My experience has led me to work on complex products in fintech, SaaS, marketing, and video games, notably for La Française des Jeux and Rauva. I work on both product creation and the maintenance of existing architecture.
I primarily focus on backend architecture design, API and business logic development, asynchronous and real-time systems, PostgreSQL and MongoDB databases, as well as cloud application deployment.
My full-stack versatility also allows me to handle interfaces in React or Next.js and deliver a complete product, from technical scoping to production.
Autonomous and product-oriented, I favor simple-to-maintain solutions that are adapted to business constraints and capable of evolving with project needs.
