• Build sleek, performant, and secure mobile interfaces that simplify complex blockchain interactions.

• Integrate wallet functionality, real-time onchain data, and LLM-driven user interactions into a cohesive mobile experience.

• Ensure high code quality through testing, code reviews, and best practices.

• Own end-to-end mobile features – from prototyping and development to deployment and iteration.

• Continuously improve the user experience based on user feedback, analytics, and emerging best practices.
