At Diletta Solutions — DPS (Diletta Pay Suite), I optimized the users and operators API module, reducing response time for CPFs with about 80 associations from about 20 seconds to 4.6 seconds.
I also redesigned the device-pairing flow across the Flutter app and Node.js APIs, strengthening account-device security and reducing the process from about three minutes to 1.8 minutes. I integrated Datarudder anti-fraud protection into the backend and develop and maintain REST microservices for financial operations.
At Diletta Solutions — ONCO and Tickets for Fun, I developed responsive interfaces, integrated REST APIs, and implemented authentication flows. Earlier, at FRST Falconi, I worked on React interfaces and Node.js APIs; I began my career as an IT Intern at UNI-RN.
