What I'm looking for

I am looking for a role that challenges my technical skills and offers opportunities for growth, particularly in full-stack and AI development.

I am a Senior iOS Engineer with over 7 years of experience in developing large-scale consumer applications, achieving over 10 million daily active users for renowned companies such as Tencent, Baidu, and Shopee. My expertise lies in Swift and Objective-C, and I have recently expanded my skill set to include full-stack and AI-powered development, launching independent web applications that showcase my versatility and commitment to innovation.

At Shopee, I led the development of core modules for ShopeePay, significantly enhancing the user experience for millions of daily transactions. My role involved refactoring existing applications to improve modularity and development velocity, which has been a recurring theme throughout my career. I have also spearheaded the adoption of React Native at Baidu, where I designed a hybrid architecture that reduced development workload and enabled real-time feature deployment.

In addition to my technical skills, I am passionate about mentoring and sharing knowledge, having conducted workshops to onboard team members onto new technologies. I am always eager to learn and grow, and I thrive in environments that challenge me to push the boundaries of technology.
