TH-002 6.0 Major Release
Goal
Drive a strategic shift from “reactive management” to a “compliance-driven model,” improving patient engagement and product satisfaction while strengthening automated intervention.
Responsibilities
Built and validated six core hypotheses around patient learning curves, feedback perception, and family compliance; redesigned patient-side task and incentive logic, strengthened real-time feedback, and optimized clinician-side automated intervention paths.
Outcomes
- Significant increase in post-discharge compliance; manual follow-up satisfaction reached 80%+.
- Product capability shifted toward automation; frequency of manual intervention by clinicians and ops dropped, with first manual intervention delayed by an average of 3 days.

ChatSprout 2.0 — LLM-Powered Scenario-Based English Communication Coach
Goal
Identify the core pain point: non-native newcomers struggle not with grammar, but with context-specific expression in high-stakes scenarios (networking, disagreeing, giving feedback).
Approach
Conducted 10+ user interviews and designed a scenario-based training system using LLM + RAG — built a scenario taxonomy from user research, with a low-similarity fallback mechanism to handle edge cases and maintain user trust.
Results
Optimized the retrieval pipeline to achieve ~80% Top-3 scenario match accuracy; established an evaluation framework (expression accuracy, tone, latency, token cost) and controlled the response time in 1.5–2s.
Key insight
In open-ended language training, retrieval quality drives generation quality more than model scale.
