About Me

The story behind the code

I'm a full-stack developer focused on building AI-powered tools for document intelligence, knowledge visualization, and infrastructure automation. Currently, I work as an IT Expert at Vector Informatik GmbH in Shanghai, where I support enterprise collaboration platforms and extend RESTful APIs for automotive tool integrations.

I studied Information Science & Technology at Penn State University, and have since built software across geospatial systems, financial risk modeling, and enterprise platforms.

Outside of work, I build tools like Pawdig (an AI document intelligence platform), open-source projects like ragviz (a Graph RAG visualization platform) and viber(a DOM capture tool for AI-assisted coding). Right now, I'm building an open-source AIOps platform that applies AI and machine learning to automate IT operations.
