• 👨‍💻 Server Engineer@Bytedance(202207–present)

• 🌱 What I care about right now:

  • Staying curious, especially when things get complex or uncertain
  • Focusing on the process rather than short-term results
  • Being brave enough to express, write, and build in public

• 🔬 What I’m spending time on: Applying LLM technologies to real-world work and life scenarios, with ongoing exploration around AICR, domain-specific workflows, VibeCoding, and beyond, while continuously learning and adapting to the fast-evolving AI landscape, and learning how to work with AI as a long-term thinking partner.

• 📖 Outside of work: I maintain regular habits of reading and writing, using periodic reflections (on life, work, and technical practice) and technical blogging as tools to think more clearly, review my progress, and grow over time, alongside learning about investing, fitness, and personal development.

• ⚡ Practicing continuous self-reflection

Trying to stay honest about what I know, and curious about what I don’t.
