Building the future,
one commit at a time.
I'm a Fullstack Engineer with over 8 years of experience building scalable web platforms, developer tools, and AI-powered applications. Currently at Apple, I develop LLM-based automation workflows and internal developer platforms.
Previously at Trip.com IBU and ByteDance Feishu, I specialized in low-code platforms, micro-frontend architectures, and AIGC tooling — enabling teams to ship 10,000+ pages and dramatically improve development velocity.
I hold a Master's degree in Computer Networks from the University of Pittsburgh (GPA 3.6/4.0) and contribute to open-source projects with 2,300+ combined GitHub stars.
