LEO ZHOU / CHANGJU ZHOU
Data Visualization Lead · Hithink RoyalFlush AI
I lead data visualization in the AI department at Hithink RoyalFlush, with a background in designing and delivering financial software. My work now centres on AI for finance and visualization: building interactive AI applications and exploring agent orchestration, evaluation, and the engineering infrastructure behind them. I focus on making model capabilities part of software we can verify and maintain.
WRITING AS DATA
294 ESSAYS01 / FOCUS
From financial web products to narrated research videos, I work on how financial information is organized, analysed, and presented. I now bring that domain experience to AI application design, including data definitions, content generation, and result validation.
Financial data storytelling ↗Building on the HiVis component architecture, I turn chart semantics, interaction rules, and rendering capabilities into protocols agents can use. Models generate specifications; code validates and renders them, with regression cases checking the effects of changes.
