Message

At Fusionix, I develop and maintain enterprise messaging platforms that centralize and process communications. I implement backend services with Node.js and NestJS, including a messaging gateway for integrating different flows.

I work with MongoDB and SQL Server, and deploy services on Microsoft Azure in production environments using agile methodologies.

On Carpooleando, I design and develop a carpooling application end to end, with Next.js, Tailwind, Zustand, Node.js, Fastify, and Prisma. I’ve implemented trip, matching, booking, permission, and state-management logic.
