Hi, I'm Yi Wang

AI Systems Builder · Full-Stack Engineer · Toronto, Canada

About Me

I am a CS student at York University focused on designing and shipping AI-native products that combine agent orchestration, reliable backend services, and strong product UX.

I care most about long-term engineering directions:

  • Direction 1 — Agentic Product Systems: building practical multi-agent workflows for real user tasks.
  • Direction 2 — Applied LLM Infrastructure: RAG pipelines, retrieval quality, and robust inference workflows.
  • Direction 3 — AI + Full-Stack Delivery: turning models into production-ready web applications with measurable outcomes.
  • Direction 4 — Developer Knowledge Platforms: documenting reproducible patterns for AI engineering and software delivery.

Contributor at OpenClaw, and actively open to collaboration on product-focused AI projects.
