What I'm looking for

I'm looking to build scalable full-stack, backend, cloud, or AI-powered products with Agile teams, where I can work on modern architecture, system integrations, testing, CI/CD, and continuous technical growth.

I'm leading the modernization of Expreso Brio's 12-module logistics system from Visual Basic to a scalable React and .NET 8 architecture. I also automated electronic invoice generation through AFIP integration, eliminating manual billing tasks.

I've built REST APIs, microservices, and production web applications for TechX, Yamana Tech, and Nash v2 using C#, ASP.NET Core, Node.js, Python, React, Angular, SQL Server, PostgreSQL, and MongoDB. My work has improved municipal system response times by approximately 30% and interface load times by approximately 25%.

I also build cloud-native e-commerce and AI applications using Docker, AWS, Kubernetes, CI/CD, RAG, LLMs, and agent workflows.
