Develop and maintain a cross-platform peer-to-peer mobile application, taking ownership of features from implementation through testing and release. Ensure the application delivers a reliable, responsive, and secure experience across iOS and Android.

• Build, refine, and maintain features for messaging, voice and video calls, media sharing, device pairing, and identity backup.

• Implement user interfaces and connect them to the peer-to-peer core APIs running directly on the device.

• Integrate native mobile capabilities, including push notifications, camera access, biometric authentication, and background tasks.

• Profile and optimize performance on real devices, focusing on application startup time, extended chat sessions, media processing, battery consumption, and network usage.

• Write and maintain unit and end-to-end tests to ensure application reliability and prevent regressions.

• Support stable releases through continuous integration workflows, crash reporting, and systematic debugging.

• Collaborate with product, design, and peer-to-peer engineering teams to deliver new features and improve the overall user experience.

• Participate in code reviews, promote engineering best practices, and maintain a high standard of code quality.
