I build Java and Go banking integrations for SWIFT payment systems.

At StoneX Brasil, I build back-end and middleware solutions for banks and financial institutions using the SWIFT messaging network.

I work primarily in Java, with Golang and functional development supporting payment, foreign-exchange, and file-translation workflows, including MT/MX conversion.

Previously, I developed ERP-related software at Lyon Engenharia, MAGIT IT PARTNER, and Nasajon Sistemas. I'm interested in network security, functional programming, code golfing, and learning new programming and natural languages.
