Future Trends and R&D Organization for Mobile Development at Xianyu

This article outlines the future trends of terminal (mobile) development and the evolving talent structure, using Xianyu's technical team as a case study. It argues that smartphones will remain the primary traffic source for the next three years, while cross‑device architectures such as ReactNative, Weex, and Flutter are becoming essential for efficient product iteration.

The author highlights how hybrid architectures reshape job roles and organizational structures, advocating for fewer, more versatile positions that reduce coordination overhead. The proposed future R&D model introduces two core roles: an Application Development Engineer who is proficient in both front‑end and back‑end technologies (a full‑stack mobile engineer), and an Infrastructure Development Engineer who builds and maintains shared containers, IDEs, and CI/CD pipelines.

To support this model, the article describes a series of infrastructure upgrades: a unified mobile container (e.g., Flutter/RN/Weex), a unified programming plane with consistent APIs for Dart and TypeScript, and a unified development workflow that blends the fast iteration of front‑end with the stability of native mobile builds.

The centerpiece is the KUN project, a high‑performance, W3C‑compliant cross‑platform rendering engine built on Flutter. KUN aims to provide high extensibility, adherence to web standards, and consistent performance across devices, reducing the complexity of maintaining multiple containers.

Finally, the author reflects on the need for continuous innovation, talent upskilling, and alignment with global best practices to maintain competitive advantage in the mobile ecosystem.
