Equipment Software & Control Systems Engineer — one person across the OT / IT / AI stack of production machinery, from PLC motion control to AI defect detection.
Graduating master's (National Central University, Opto-Mechatronics) with ~4 years of hands-on equipment-control experience. Sole author of the control software for automation machinery across corrugated-board, textile and biotech lines — from spec, through implementation, to volume production on the factory floor.
- OT control — multi-vendor PLC (Mitsubishi FX/Q · OMRON NX · Keyence · CODESYS) · Structured Text · PLCopen motion · non-linear state machines · multi-axis synchronization (up to 44 axes) · EtherCAT
- IT integration — industrial Linux / PREEMPT_RT · CPU isolation · Modbus TCP/RTU · OPC UA · RESTful API · shared-memory IT/OT bridging
- AI inspection — PyTorch · fine-grained defect detection · custom hierarchical classification head
- EKGMonitor — a C# / WinForms data-acquisition & persistence pipeline (graduate coursework), paired with a structured defect review I wrote a year later: five documented defects, one of them silent (an unsynchronized counter that can shift every CSV sample index by one). The review is the point, not the code.
- codesys_template_public — machine-agnostic CODESYS Control for Linux + Go + Svelte skeleton (MIT). A shared-memory IT/OT bridge with a versioned seqlock contract and compile-time size assertions: it refuses to map on layout mismatch rather than pass torn data on as valid. An MVP — architecture settled, details still being refined.
- coffee_bean_detection — master's thesis: fine-grained defect detection on washed coffee beans (PyTorch; HCCH hierarchical classification head for output-logic consistency).
- DRV-Modbus — Delta DRV robot Modbus control library, repackaged with a more ergonomic class interface (address map based on @liaochikon's work, fork retained).
