- Built a full-stack Vietnamese pet e-commerce platform with product discovery, checkout, payment, order management, customer support, forum, and role-based admin workflows.
- Designed and implemented Catbot, an agentic RAG assistant with planner-enforced tool calling, hybrid retrieval, pet-care knowledge grounding, pet-profile personalization, deterministic product-safety checks, streamed responses, verified product-card rendering, and human handoff.
- Created an AI evaluation pipeline with 50 LangSmith-traced cases using LLM-as-judge scoring; achieved 96% pass rate, 97.0 average final score, 0% eval error rate, 100% required-tool/tool-order/safety/handoff accuracy, and 11.16s p50 / 22s p99 agent latency.
