Johan Alexander Rosario Lopez

I'm building secure, scalable full-stack web applications using React, Node.js, REST APIs, JWT authentication, and real-time communication with WebSockets.

For MiDulceHogar, I developed a real estate platform for listing and managing sale and rental properties, with maps, real-time messaging, a Node.js and Express REST API, Prisma ORM, JWT authentication, and bcrypt password encryption.

I also built a Django and PostgreSQL CRM web management system with client, product, order, and billing CRUD functionality, user authentication, an admin panel, and optimized dashboard navigation.

I've supported Azure resources, VDI operations, security, and process automation as a Technology Intern at Banco Popular Dominicano, and I bring experience in hardware maintenance, workstation configuration, GitHub, Jira, Jenkins CI, and ArgoCD.
