## About

```text
At Cakto, I redesigned the payment refund flow with a 24-hour reversal window and added deterministic validation rules to address inconsistent payment states across checkout flows. I also tightened seller account security with OTP-based email verification.

At Tupi, I developed the BYD Recharge infotainment app, supporting the onboarding of 330,000+ registered drivers in 2025. I also replaced WebSocket streams with controlled polling and location-based updates, reducing bandwidth usage by over 95%.

At Capgemini, I worked on digital banking solutions for the Banco do Brasil mobile app. I redesigned international transfer flows, reducing average transaction completion time by 50%, and improved accessibility across banking screens.

Earlier, at Jumptec, I delivered product simulators, admin dashboards, and websites, and migrated a legacy PHP monolith to Laravel. I’ve focused on frontend development since 2016, building web and mobile interfaces with React, React Native, and TypeScript.
