What I'm looking for

I am looking for opportunities that foster innovation and collaboration, where I can leverage my skills in Java and system design to contribute to impactful projects.

I am a dedicated Back-End Engineer with a Master's degree in Mechanical Engineering from HuaZhong University of Science and Technology. My professional journey has been marked by a strong focus on Java development, where I have successfully led projects at PayPal and other notable companies. My experience includes designing system architectures, optimizing performance, and ensuring seamless integration of external systems.

At PayPal, I spearheaded the design and implementation of critical projects such as the Merchant Accounts Management and Shopping Cart systems. My efforts in performance optimization resulted in a significant reduction in latency, enhancing user experience. I thrive in collaborative environments, coordinating cross-functional teams to achieve project goals and deliver high-quality solutions.
