Built and led the frontend technical team (iOS, Android, Web). Defined team workflows and enforced code quality standards. Designed client-side data caching solutions to enhance app data loading speed. Architected K-line data caching solutions, significantly improving chart loading performance. Researched and introduced new frontend technologies. Championed the adoption of Tauri 2.0, enabling a single codebase to produce applications for iOS, Android, PC, and Desktop (macOS + Windows) platforms. Successfully deployed these apps to App Store and Google Play. Led frontend security vulnerability remediation; maintained a record of zero successful attacks. Designed a dynamic domain switching solution for apps, enabling automatic failover to backup domains if primary domains are blocked, and automatically selecting the fastest available network route. Conducted core code reviews for team members. Oversaw the design of frontend SDK abstractions, integration documentation, and third-party SDK integrations. Implemented internationalization/multi-language support using Weblate across the frontend. Developed custom scripts for one-click translation updates. Researched and implemented solutions for successfully listing exchange-type apps on App Store, including code and static resource obfuscation techniques to mitigate risks associated with 'shell apps'. Successfully listed multiple exchange apps. Authored and maintained external technical documentation. Organized internal trading competitions (spot, futures, options) to deepen team understanding of business logic. Researched Google Play policies and guided the team through successful app listings. Led the automation of internationalization workflows using Weblate for centralized translation management (app/web) and script-based updates. Designed and implemented encryption for critical configurations, allowing updates (e.g., domain changes) without requiring app re-release. Organized and documented frontend code (app/web) for potential codebase sales to merchants.

Hired, built, and managed the frontend technical team (iOS, Android, Web). Oversaw frontend development progress, quality, and conducted code reviews. Designed a unique app link switching mechanism to counter frequent domain blockings. Established the 'Code Branch Management Specification'. Contributed to iOS development (Swift), led TestFlight (TF) distribution channel setup, designed TF-specific features, and managed signature provider selection and integration. Developed Android market data features (Kotlin). Addressed and resolved high-risk warnings for the Android app. Led 3 rounds of performance optimization initiatives with significant results. Oversaw system design for core project requirements, organized design refinement, and implementation. Managed frontend releases, monitored app performance in production, integrated Bugly, and resolved live bugs.

Built the frontend technical team from scratch (iOS, Android, Web). Managed development progress, quality, and conducted code reviews. Spearheaded the launch and new feature development for ExShell's four platforms. Developed key frontend pages (Home, Assets, Trading) using native JS/HTML/CSS. Contributed to iOS (Obj-C/Swift) and Android (Java/Kotlin) feature development. Collaborated with backend developers on API design. Managed relationships with iOS signature providers and arranged app signing.

Oversaw all technical teams (Frontend, Backend, DevOps, QA, Animation). Formulated and implemented technical strategies. Solved critical technical challenges. Participated in client meetings and decision-making. Actively contributed to development (iOS/Android/Web/H5/Java - primarily frontend), participating in over 10 projects.

Research and implementation of image processing algorithms (C++). Contributed to the development of 4-5 applications. Responsible for drafting patent reports. Developed algorithmic platforms.
