Design and review hybrid or partial-native architecture, including WebView integration, JavaScript bridges, native plugins, and communication between native applications, web-based content, and backend APIs.
Lead optimization of cold-start and warm-start time, memory usage, WebView performance, large assets, network handling, application responsiveness, crash rates, and Android ANRs.
Design and improve dynamic content download and update mechanisms, including packaging, caching, resumable downloads, integrity validation, atomic installation, version compatibility, failure recovery, and rollback.
Ensure application stability under slow, unstable, or overseas network conditions and recover safely from interrupted downloads, application restarts, incomplete packages, and failures after content updates
Govern compatibility and release sequencing across Android and iOS application versions, web content packages, backend APIs, and third-party SDKs, including backward compatibility, staged rollout, hotfix, and rollback.
Manage Android and iOS build configurations, signing, certificates, provisioning, CI/CD, and releases through Google Play, Apple App Store, and Huawei AppGallery where applicable.
Investigate production incidents using application logs, crash reports, Firebase Crashlytics, Android profiling tools, Xcode Instruments, and other monitoring tools; lead root-cause analysis and preventive improvement.
Establish and enforce native development standards for architecture, coding, security, testing, branching, versioning, documentation, deployment approval, and release governance.
Review vendor-developed source code, technical documents, and test evidence; conduct code-level technical discussions and verify claimed performance or stability improvements with objective results.
Coordinate with frontend, backend, QA, infrastructure, security, business, and vendor teams, and support platform-specific automated testing and Appium-based end-to-end testing.
Maintain current technical documentation for native architecture, modules, interfaces, dependencies, build configurations, release procedures, troubleshooting, and operational recovery.
