MES & OT-IT Integration
Expertise in machine-to-MES architecture, OPC UA information modelling, NodeSet engineering, data contracts, state synchronization, production and result data interfaces, and PLC-to-database integration across large-scale manufacturing environments.
PLC & Automation Platforms
Hands-on experience with Beckhoff (TwinCAT), Siemens (TIA Portal, WinCC), Allen-Bradley (Studio 5000, FactoryTalk), B&R, Omron, and WAGO for designing and commissioning complex automation systems.
Systems Architecture & Control Design
Proficiency in automation architecture, functional requirement translation, system decomposition, control modes and state machines, interlocks, interface specification, and FAT/SAT commissioning.
Industrial Communication
Knowledge of OPC UA, MQTT, Modbus TCP/RTU, CAN/CANopen, Industrial Ethernet, and REST APIs for robust machine and system connectivity.
Software & Data Engineering
Development of industrial applications using Structured Text (IEC 61131-3), C#, Python, SQL, XML, and JSON, including data modelling and automated engineering tools.
C# Engineering Tools Development
Development of custom C# tools to automate NodeSet generation and transformation from structured JSON/XML interface definitions, reducing manual engineering effort and improving interface consistency.
PLC-to-SQL Interface Design
Implementation of high-performance PLC-to-SQL interfaces that significantly reduce database write latency while improving determinism and maintainability.
Industrial Connectivity Platform Development
Design and development of modular industrial connectivity platforms for integrating PLC and machine data with higher-level IT systems through OPC UA, MQTT, and REST APIs using C#/.NET.
FAT/SAT & Commissioning
Execution of factory acceptance testing and site acceptance testing for large-scale automated sorting, conveyor, and packaging systems, including functional testing and troubleshooting.

Project history
Designed and implemented OT-IT and machine-data interfaces for large-scale battery-cell manufacturing (PowerCo/Volkswagen Group). Engineered OPC UA information models and NodeSets, developed C# engineering tools for NodeSet automation. Designed MES integration architectures for Continental and First Solar including PLC-to-SQL interfaces. Delivered automation and commissioning for marine electrification projects (Danfoss Editron). Delivered control-system improvements for industrial machinery and developed custom industrial software using C#, Python, and SQL.
Designed and developed a modular industrial connectivity platform for integrating PLC and machine data with higher-level IT systems through OPC UA, MQTT, and REST APIs. Defined protocol abstraction, configuration, and data-storage architecture in C#/.NET to simplify OT-IT integration for small and medium-sized manufacturers.
Commissioned large-scale automated sorting and conveyor systems, performing functional testing and FAT/SAT validation. Diagnosed interactions between mechanical equipment, sensors, actuators, and PLC control during system start-up and troubleshooting.
