What I'm looking for

I'm looking for opportunities that challenge my skills and foster innovation.

I'm Xu Wang, a Senior Backend Engineer with a strong background in developing scalable web applications. Currently, I lead backend development for innovative projects like Sonorus, a Web3 music-sharing ecosystem, and Bounce, an LLM-driven sports aesthetics platform. My expertise lies in designing core modules that enhance system performance and user experience.

Throughout my career, I have successfully integrated advanced technologies such as blockchain and LLM ecosystems to optimize real-time data processing. My previous roles at Bytedance and HUPU allowed me to refine my skills in backend engineering, where I focused on enhancing ad delivery platforms and developing recommendation systems. I take pride in my ability to streamline workflows and improve system performance through continuous optimization.
