ColombiaWhat I'm looking for
I am a systems engineer and senior software architect with 14 years building web and software solutions using the Microsoft .NET ecosystem, C#, and related front-end frameworks like React, Angular and Blazor. I specialize in application architecture, microservice design, and cloud-native development on Microsoft Azure, with a strong track record of improving observability, CI/CD pipelines, and reducing technical debt across large enterprise projects.
Across engagements for clients including Disney, Kantar, PwC, EPAM and Globant, I led backend and full-stack development, migrated legacy systems to modern frameworks, and delivered underwriting, payments and platform microservices. I emphasize test-driven development, automated deployments, and collaborative agile delivery to produce reliable, maintainable software that meets business goals.
