onchu.tech — Keep It ON

I fix what your .NET and industrial systems are stuck on.

ABP Framework · HALCON Machine Vision · WPF HMI · Kubernetes
Based in Wuhan, China — working globally.

10 years building enterprise software and industrial automation systems. I've debugged ABP multi-tenancy issues at 2am, calibrated GigE cameras on factory floors, and migrated .NET Framework systems to Kubernetes.
Now I help teams like yours do the same — faster.

Two worlds, one engineer

Enterprise software and industrial automation rarely overlap. William works in both — end to end, from architecture to factory floor.

SOFTWARE / .NET

Enterprise .NET & Cloud

ABP Framework, microservices and Kubernetes — built for systems that cannot go down.

ABP Framework: multi-tenancy, permissions, DDD, modular architecture
Dapr microservices & .NET 8 APIs in production
.NET Framework → .NET 8 cloud migration on Kubernetes / k3s
AI integration: Semantic Kernel and LLM APIs inside .NET systems

INDUSTRIAL / AUTOMATION

Machine Vision & HMI

HALCON, WPF HMI and PLC communication — software that runs on the factory floor.

MVTec HALCON inspection: GigE cameras, shape matching, defect detection
WPF / WinForms industrial HMI with real-time visualization
PLC communication: Xinje, Modbus RTU/TCP, EtherCAT
Servo & motion control retrofits (open / closed loop)
