What I'm looking for

I seek senior engineering roles where I can lead architecture and R&D teams, build scalable systems, drive AI/LLM initiatives, and collaborate cross-functionally to align technical strategy with business growth.

I am a versatile architect and engineering manager with over 10 years of experience in internet and e-commerce technologies. I design scalable, high-performance microservices and have led 0-to-1 platforms including a digital reading app serving 300K+ daily active users and multiple AI initiatives.

At JD.com I led architecture and R&D teams, driving system stability, global integrations, and cross-functional projects such as AI writing tools, equipment leasing, and international merchant onboarding. I hold an MSc in Computer Application Technology and previously developed core systems as a senior software engineer, combining technical leadership with product-aligned strategy.
