Backend Engineer

 I'm a Software Engineer with 3 years of professional experience at Tencent, where I worked with C++, Go (Golang), and Python.

I hold an M.S. in Computer Science from the University of Hong Kong and a B.S. in Software Engineering from Nanjing University. I also have a competitive programming background, including experience in China's National Olympiad in Informatics (NOI) competition system, which helped me develop strong algorithmic thinking and problem-solving skills.

Beyond my professional work, I enjoy building products independently and exploring emerging technologies.

Projects & Hackathons

  • ETHGlobal Hackathon (Solo Hacker): Independently participated in ETHGlobal, working on a Web3 data infrastructure project involving The Graph, customizable on-chain data APIs, and x402 payments.
  • AI & LLM Applications: Developed experimental applications involving real-time multimodal AI, voice interaction, and LLM-powered agent workflows.
  • Independent Projects: Experienced in taking ideas from initial concepts to working prototypes, handling architecture, backend development, and integration independently.

What I'm Looking For

I'm seeking fully remote opportunities as a Backend Engineer, Software Engineer, or Infrastructure Engineer, particularly with international teams working on Web3, AI, developer tools, or distributed systems.

I value technical ownership, challenging engineering problems, and the freedom to build impactful products.
