About

I am a Computer Science Engineer with experience developing full-stack applications using Angular and .NET Core. I have worked with clean architecture, secure authentication (JWT, AWS Cognito), and task automation in real-world environments. I am actively involved in the design and improvement of modular, scalable, and production-ready systems.

I have practical experience applying machine learning techniques, including clustering and evolutionary algorithms such as genetic search, focused on solving real-world problems in different domains. Currently, I am focused on growing as a versatile developer, with end-to-end skills ranging from backend development with microservices to artificial intelligence integration and automation of complex workflows.
