Project description:
"I need a robust, well-documented RESTful API that can 1) pull live and historical stock quotes, 2) ingest and process personal-finance transactions (CSV, Plaid or similar), and 3) track multiple cryptocurrency pairs and on-chain wallet balances. The API must handle data retrieval and complex calculations, expose role-based user authentication (JWT or OAuth2), and be structured so that additional endpoints can be added without breaking existing calls.

On top of that backend I want a clean, responsive mobile interface released for both iOS and Android from a single codebase—React Native or Flutter is fine as long as the final build runs smoothly on the latest OS versions. The app should surface real-time charts, portfolio summaries, and a simple wallet section while keeping the navigation intuitive for non-technical users.

Deliverables:
• Source code for the API with unit tests, docker-ready deployment files, and setup instructions
• Full mobile app source, ready-to-publish builds, and a brief style guide so new screens match the existing UI
• Postman (or similar) collection documenting every endpoint and typical responses
• One short hand-off session walking through deployment and store submission steps

The project is complete for me when the API passes the tests, the apps install from TestFlight/Play Internal Testing without crashes, and sample data flows end-to-end in under three seconds per request." (client-provided description)
