// About
Hi, I'm William.
I'm a .NET engineer and industrial software developer based in Wuhan, China. I build and fix things in two worlds that rarely overlap: enterprise .NET software and industrial automation.
The software side
I work deeply with ABP Framework — multi-tenancy, permission systems, DDD architecture, Dapr microservices, and cloud migration. I've led the development of a pharmaceutical clinical supply chain system, built Kubernetes-based microservice platforms, and integrated AI (Semantic Kernel / LLM APIs) into production .NET applications.
The industrial side
I develop upper computer software (WPF/WinForms HMI), work with MVTec HALCON for machine vision inspection, and handle PLC communication (Xinje, Modbus, EtherCAT). My most recent project was a label defect detection system for a textile label manufacturer in Dongguan — inspecting labels at production speed across multiple design variants.
Why onchu?
I operate through onchu.tech (Wuhan Baisheng Media Technology Co., Ltd.). The name comes from a simple idea: keep it ON, hit the target CHU (中). That's what I do — keep your systems running, hit every requirement precisely.
Currently available for
- Remote consulting (hourly / project-based)
- Industrial HMI & machine vision development
- ABP / .NET architecture reviews
- Longer-term embedded team work
