PicPay

Payment App, Credit and Debit Card Manager, Investment Tools

PicPay, a widely-used digital wallet app in Brazil, was designed with millions of users in mind. Its primary focus is to provide convenience, user-friendliness, accessibility, and robust security, making it a trusted platform for everyday transactions and payments. To bring about large-scale features, I utilized the following technologies:

UIKit and programmatic layout for designing interfaces.
MVVM, Coordinator, and Modular architecture for flexibility and scalability.
Keychain for securely storing sensitive data.
Push notifications for real-time updates and engagement.
Camera integration for scanning QR Codes and Bar Codes.
Dispatch queues handling asynchronous flow and ensuring optimal performance.
REST API connections to facilitate communication with external services.
Analytics tools for monitoring usage and gathering insights.

Home screen

I developed a dynamic banner system for quick and convenient remote configuration. I also enhanced the suggestion list and implemented additional elements within the scroll view using the Texture framework, prioritizing performance.

Wallet

I played a role in redesigning the entire wallet feature, ensuring accessibility for screen readers. This included implementing a credit/debit card manager for seamless management.

Savings

At PicPay, I contributed to the creation of a flexible savings account that allows users to organize their savings using virtual Piggy Banks. I was involved in the project from its inception, including design research and refinement.

Statement

Together with my team, I built a simplified statement screen that unified all transactions from different microservices within the app. This provided users with a comprehensive overview of their activities.
