Senior Flutter Developer at Genial Investimentos building a digital bank and its credit card app.

Brazil
Message

At Genial Investimentos, I contributed from the beginning to an app that evolved from an investment portfolio into a digital bank, launched in February 2024. I’m the principal mobile developer for its credit card app, contributing to features including PIX, bill payments, security, and authentication.

At Genial Investimentos, I also implemented CI/CD, automated tests, internationalization, and performance optimizations. The modular app uses micro frontends and is white label for BRB and Porto Seguro.

At BF Holding, I architected and developed Flutter credit card features and built a Tap to Pay app using native Kotlin and Swift modules. I also implemented mobile performance monitoring with Grafana and an open-source stack; earlier, at BPS Sistema de Automação, I developed Flutter apps for remote control of industrial equipment.
