I design and implement custom HMI and SCADA middleware solutions in C# for industrial automation environments. My work bridges the gap between physical machines (PLCs) and client-facing software, delivering reliable, real-time control and monitoring systems.
What I offer:
- Design and development of HMI web portals for manual and automated machine control
- OPC UA and socket telegram communication interfaces between software and PLCs
- Real-time machine state visualization services (machine status, channels, trays, alarms)
- Custom control strategies for product monitoring, storing, releasing, and inventory buffering
- Integration with client WMS or ERP systems via HTTP, XML, and JSON
I have hands-on experience building end-to-end middleware for automated warehousing machines used as production buffers and storage units in large logistics operations. My solutions are tailored to each client's operational strategy, not off-the-shelf.
If you need a reliable engineer who understands both the hardware side (PLC signals, OPC UA) and the software side (backend services, web portals, system architecture), I can deliver exactly that.
Technologies: C#, OPC UA, TCP/IP Sockets, REST APIs, XML, JSON, SQL
Please note: OPC UA licensing fees are not included in the service rate and are to be covered by the client. Depending on the project scope and hardware vendor, these licenses can represent a significant cost and will be scoped and communicated transparently before engagemen
