What I'm looking for

I want to modernize and build secure, scalable .NET/Azure systems end-to-end—owning architecture, APIs, CI/CD, and containerized deployments—while collaborating in agile Scrum teams where I can mentor others and deliver measurable client value.

I’m a Senior Software Engineer with over 8 years designing, developing, and deploying complex software solutions across the Microsoft .NET ecosystem and Azure cloud. I specialize in application modernization—leading migrations from .NET Framework to .NET Core, from SOAP to REST APIs, and from monolithic architectures to microservices—grounded in Clean Architecture, Hexagonal Architecture, and SOLID principles.

I bring strong end-to-end ownership across the software development lifecycle in a DevOps culture, implementing CI/CD pipelines with Azure DevOps and Jenkins, and containerizing with Docker for deployment across Azure services like App Services, Azure Functions, AKS, and Azure SQL Database. I ensure quality with xUnit/Jasmine and tools like SonarQube, and I’ve delivered high-impact outcomes for clients including Coca-Cola, Tesla, Rappi, and Grupo Éxito—often under Scrum—while also training teams, collaborating with clients, and proposing practical technical feasibility solutions.
