About Ricardo

I am a Full Stack Developer and Software Architect with a Bachelor's degree in Computer Science and a Master's degree in Data Science currently in progress. For over ten years, I have been developing complex software solutions, web applications, and data-driven systems.
I am currently available as a freelancer – for backend and frontend development as well as for the conception and implementation of software architectures.

My focus is on developing scalable and maintainable systems and on transforming data into real business value – from robust backends with ASP.NET and PostgreSQL to high-performance web applications with Angular. Furthermore, I have extensive experience in Data Analytics, Machine Learning, and modern deployment strategies with Docker and Kubernetes.

In my professional career, I have led development teams, accompanied digital products from idea to successful implementation, and made significant contributions to the development of stable, reliable software that creates real business value.
