1. Core Business Development

• Responsible for the Flutter cross-platform development of core modules for the DEX exchange (trading pairs, order book, wallet management, K-line charts, etc.), ensuring a high-concurrency, low-latency trading experience.

• Optimize trading interface rendering performance, addressing critical issues such as animation stuttering and data synchronization delays.

• Integrate blockchain APIs (such as WebSocket real-time market data and smart contract interactions) to ensure data security and stability.

2. Architecture and Technical Challenges

• Design a layered architecture based on Flutter + Dart (such as modularization and state management), leading technology selection and code standard formulation.

• Resolve technical challenges in complex business scenarios (such as hot wallet encryption and multi-chain asset management).

3. Cross-Team Collaboration

• Collaborate with the backend team to define gRPC/GraphQL interfaces and align with the product team on financial-grade functional requirements (such as compliance KYC and AML).

• Participate in the formulation of mobile security strategies (data encryption, anti-tampering, permission control).
