Project description:
"I’m building a sophisticated personal-finance mobile application that must feel seamless on both iOS and Android. At its core the app will give users crystal-clear visibility into their money through real-time budget tracking and precise expense categorization. Every screen, workflow, and API call has to respect the security, privacy, and UX standards that today’s fintech users expect.

Here’s what I need from you:
• End-to-end development of the mobile clients in Swift/SwiftUI and Kotlin (or a high-performance cross-platform framework if you can prove parity).
• A clean, well-documented architecture that supports future expansion—think investment tracking or goal setting down the road.
• Integration with bank-data aggregators (Plaid, MX, or similar) for automatic transaction import.
• Backend endpoints, user authentication, and encrypted data storage built with a scalable stack you’re comfortable owning.
• A polished interface that passes App Store and Google Play design guidelines.
• Source control in GitHub and CI/CD pipelines so I can test TestFlight and internal Android builds on schedule.

Acceptance criteria will revolve around: zero-crash beta builds, accurate categorization logic against a supplied test data set, and a responsive UI at 60 fps on mid-range devices.

Because of regulatory considerations and easier collaboration, I’m only hiring developers or teams physically located in the United States—no exceptions. Please mention your state in your reply and share one comparable fintech project you’ve shipped so I can jump straight into technical discussion." (client-provided description)
