Experience

  • g2 Recruitment GMBH. / Inertec Löttechnik GmbH-
    PLC Software Developer (Contractor)
    March 2025 - September 2025 (6 months)
    Kreuzwertheim, BY, Germany
    As part of a project for soldering machines, I was responsible for system integration, software development, and creating tools supporting diagnostics and data archiving. The work was carried out using TwinCAT 3, TF2000, and TF6420 technologies.
    • Integration of Oracle DB and Beckhoff PLC for MES communication – setup of a test Oracle DB server, code
    implementation, PLC configuration, and development of an HMI visualization. The solution was designed to enable future scalability and seamless integration with other types of databases..
    • Development of software for Keyence scanners (stationary and handheld) – implementation of simulation and step modes, advanced error handling, diagnostic modules, and an intuitive HMI interface. The
    improvements significantly enhanced system stability, operator usability, and efficiency in testing and maintenance.
    • Implementation of an object-oriented text data archiving system – designed with a modular, object-oriented architecture that ensures maintainability and extensibility. The system provides reliable file-based data
    storage, advanced diagnostics, and serves as a solid foundation for further projects.

    September 2024 - February 2025 (5 months)
    Waterford, Ireland
    Commissioning and software development of a tray palletization machine for the pharmaceutical industry using Beckhoff TwinCAT3 and Han's Robots.
    • Developed an algorithm in Python to determine pallet positions based on 3 reference points from the robot's scan, enabling precise tray placement calculation.
    • Optimized Modbus communication between the robot and PLC, reducing response time from 1.5s to 0.1s.
    • Implemented HMI improvements using TF2000 (TwinCAT3 HMI server), enhancing usability and
    performance.
    • Improved operational efficiency by reducing the robot's pick-and-place cycle time from 13s to 9s and pallet scanning time from 55s to 30s.
