Software Engineer / AI Engineer
My legal name is Weixi Guan. I’m from Canton (Guangzhou), China, and I bring 2+ years of professional experience in software engineering.
I’m a software engineer who likes the messy middle of products: where business workflows, data, and user-facing screens need to become one usable system.
Recently my work has been around Microsoft cloud, automation, and full-stack product engineering. The part I care about most is clarity: simple paths for users, sensible system boundaries, and code that can survive the next change.

The University of Melbourne
Royal Melbourne Institute of Technology (RMIT) University
Royal Melbourne Institute of Technology (RMIT) University
Designed and implemented an enterprise document processing solution using Azure AI Content Understanding to automate structured data extraction from application forms and invoices. The system supports both single-format pipelines and complex multi-format scenarios by training multiple extraction models and routing documents through classifier-based workflows. It exposes unified inference outputs as structured JSON for Power Automate, Dynamics 365, Power Apps, and other frontend systems.
