Backend-focused .NET developer building scalable microservices and optimizing data-heavy systems.

What I'm looking for

I seek backend or fullstack roles where I can design scalable microservices, optimize data/reporting systems, work in Agile teams, and grow into technical leadership.

I am a backend-focused .NET developer with hands-on experience building scalable microservices, optimizing reporting pipelines, and delivering reliable financial and enterprise platforms. I have contributed to products across finance, insurance, ERP, and healthcare, improving performance and reliability through CQRS, EF Core, and cloud-native practices.

I combine pragmatic engineering with a product-aware mindset—applying Clean Architecture, automated deployments, and Agile/Scrum to reduce processing times and increase system reliability. I am fluent in Spanish, advanced in English and Portuguese, and hold a Product Owner certification.
