What I'm looking for

I’m looking for Full Stack Software Engineering opportunities where I can combine my frontend expertise with backend and cloud experience, contributing to complex products, scalable architectures, and end-to-end software solutions.

At Itaú Unibanco, I worked on Íon for Advisors, an investment advisory platform used by thousands of investment specialists. I contributed to a growing ecosystem of 17+ microfrontends built primarily with Angular, React, and TypeScript.

I worked with Nx Workspaces and monorepos, and contributed to reusable Angular libraries and shared components. I also integrated frontend applications with REST APIs and contributed to .NET and C# services and AWS Lambda workloads.

My earlier work included frontend development for the Conta Digital Linx project at Sys3 Sistemas, including the Kitchen Display System and Portal Conta Linx. I’m currently focused on Full Stack Software Engineering opportunities where I can combine my frontend expertise with backend and cloud experience to contribute to complex products, scalable architectures, and end-to-end software solutions.
