Hi, I'm Cheng Feng.

I build tools that turn messy information into something I can read at a glance. This site collects the projects I am working on and what I learn from them: AI research tools for investing, graph machine learning, and data pipelines.

Projects

• Invest-Assistant: A personal investing dashboard where AI agents research a company and the page shows the result as charts.
• Company Graph: A relationship graph of competitors, suppliers, customers and partners across roughly 500 large US companies.
• Graph Neural Networks: Small, readable GraphSAGE and temporal graph network demos for link prediction.

See all projects or read the blog.
