👋 About Me

I'm a Boston University Computer Science alumnus and an AI Agent Engineer building reliable agent systems and production-ready AI applications.

My work spans:

  • Agent systems: orchestration, tool use, skills, context, and session management

  • Reliability: automated evaluation, regression testing, observability, and failure recovery

  • AI applications: voice-first products, browser agents, desktop apps, and full-stack delivery

  • Engineering: Python, TypeScript, FastAPI, React / React Native, Electron, PostgreSQL, and Redis

  • 📫 Reach me via email: yshan@bu.edu

Open source

I contribute upstream fixes around reliability, security, and cross-platform desktop behavior.

👋 About Me

I'm a Boston University Computer Science alumnus and an AI Agent Engineer building reliable agent systems and production-ready AI applications.

My work spans:

  • Agent systems: orchestration, tool use, skills, context, and session management

  • Reliability: automated evaluation, regression testing, observability, and failure recovery

  • AI applications: voice-first products, browser agents, desktop apps, and full-stack delivery

  • Engineering: Python, TypeScript, FastAPI, React / React Native, Electron, PostgreSQL, and Redis

  • 📫 Reach me via email: yshan@bu.edu

Open source

I contribute upstream fixes around reliability, security, and cross-platform desktop behavior.
