@carlosandresperez

Senior .NET engineer at Valtech building .NET 8 services with Clean Architecture and Kafka.

At Valtech, I develop and maintain enterprise applications across .NET Framework, .NET Core, and .NET 8. I design .NET 8 solutions with Clean Architecture and optimize SQL Server data access.

I implement message-driven, distributed systems with Apache Kafka, CQRS, and MediatR, and manage CI/CD pipelines with Azure DevOps. I also containerize services using Docker.

Previously, at Itehl DTS, I contributed to decomposing a monolithic application into microservices while keeping the existing system operational. I led teams of 5–15 developers and built microservices with ActiveMQ.
