I'm a Computer Science Engineering student based in Havana, Cuba, focused on developing full-stack applications, backend services, and software solutions for real-world problems.

My experience includes e-commerce platforms, business management systems, multi-tenant applications, payment integrations, automation, and network-oriented software. I enjoy working across the development lifecycle, from frontend implementation and API design to database integration and system deployment.

Beyond application development, I explore networking, systems programming, and multiplayer infrastructure for games. These projects allow me to investigate technical problems at different levels of the software stack.

• Primary focus: Full-stack and backend engineering
• Frontend: React, Next.js, Angular, JavaScript, TypeScript
• Backend: NestJS, Django, C#/.NET, Go, REST APIs
• Data: PostgreSQL, MySQL, MongoDB, SQLite, Redis
• Integrations: Payment providers, external APIs, automation, multi-tenant systems
• Additional interests: Networking, systems programming, game networking, and AI-powered applications
• Location: Havana, Cuba
• Opportunities: Open to remote software engineering roles and collaborative projects
