Project description:
"I already have an Android Studio project that compiles, but the core money-making engine still needs finishing touches. The existing code handles login, basic UI, and wallet connectivity; what I am missing is the rock-solid execution layer that can:

• Trigger real-time arbitrage trades between target exchanges
• Open and settle flash loans on-chain within the same transaction
• Run the whole sequence automatically, hands-free, once profitable spreads appear

To achieve this you will need to wire in reliable financial data APIs for live prices, complete the trading/loan logic, and harden the scheduler with proper error handling and retries. Clean, well-commented Kotlin (Java is acceptable) is a must.

Deliverables
- Reviewed and refactored source so it follows Android best practices
- Integrated price feed via my chosen financial data API(s)
- Fully functional arbitrage + flash-loan module, callable from the current UI
- Automated execution engine with configurable thresholds and safety checks
- End-to-end test cases proving successful loan, trade, and repayment in a single run
- Final signed APK and updated source in Git

I will supply the current Git repo, API keys, and exchange credentials. If you have previous DeFi, Web3j, or ethers-android experience that will be a plus, but solid Android and REST/WebSocket know-how is essential. Let’s get this app ready for production." (client-provided description)
