Hello! I'm Neiser

I'm a fullstack developer with experience in cloud-native technologies. Currently working with Go, NestJS, React, Kubernetes and microservices architectures, building scalable and robust systems.

My stack includes NestJS, TypeScript, Angular, Python, Springboot, React, and the entire DevOps ecosystem with GitLab CI/CD y GCP.

I create educational content on YouTube and my blog, sharing practical tutorials, real-world solutions and my experience with modern technologies. My goal is to help other developers master these technologies.
