About

Key Contributions
- Own and deliver end-to-end iOS features for enterprise banking applications, collaborating closely with product managers, business analysts, architects, designers, and backend teams.
- Design and build RxSwift-based business logic with strong architectural boundaries and 90%+ unit test coverage, improving reliability, regression safety, and long-term maintainability.
- Build and enhance core banking features including account grouping, virtual card requests, and cash advance PIN retrieval, supporting business rules for sub-limit configuration.
- Execute secure mobile banking flows, including in-app credit card activation using RSA public-key cryptography to safely transmit sensitive user data.
- Create a configuration-driven dynamic menu system enabling runtime updates (add/remove/hide items, title and subtitle changes) without requiring app releases, reducing operational overhead.
- Enable faster and safer delivery by simulating backend APIs during development, supporting parallel workstreams and reducing dependency-related blockers.
- Execute platform upgrades and long-term support releases (including the 2023.09 LTS) across multiple banking applications, ensuring stability, compliance, and uninterrupted service for regional banking markets.
- Reduced regression testing time by ~58% by implementing end-to-end UI automation using XCTest for the China Bank Retail Mobile Application. Automated 700+ test cases covering critical user journeys, integrated with CucumberStudio to improve coverage and reliability, while leveraging AI-assisted tools (Cursor SDE, Composer, Claude Opus) to enhance productivity and test quality.
