About Carlos

Developing end-to-end .NET applications, from architectural design to production deployment, helping companies and startups build scalable, maintainable, and growth-ready solutions.

I can handle the entire development cycle: architecture definition, backend development with .NET, APIs, Blazor applications, system integration, databases, deployment with Docker and Kubernetes, and production deployment on VPS or cloud platforms. I work by applying modern architectures based on SOLID, Domain-Driven Design, CQRS, and event-driven architectures to build robust and easily evolvable solutions.

One of my core values is the ability to quickly analyze a problem and turn it into a sustainable solution, avoiding over-engineering. I adapt quickly to existing projects, identify critical points, and propose improvements that add value from the early stages of development.

Furthermore, I incorporate Artificial Intelligence tools into my workflow to accelerate development, improve code quality, automate repetitive tasks, and reduce delivery times, always maintaining technical judgment and the quality of the final result.

I typically collaborate on projects such as:

Developing .NET applications from scratch.
Designing backend architectures and microservices.
REST APIs and distributed systems.
Enterprise applications with Blazor.
Modernizing legacy applications.
Containerization with Docker and deployments on Kubernetes.
Deployment automation (CI/CD).
Cloud migrations and performance optimization.

My goal is to deliver solutions that not only work today but can also be easily maintained and evolved as the business grows.
