About me

Senior Automation Engineer specializing in PLC programming and commissioning of industrial machines and production lines. Experienced in robotics, motion control, and industrial communication. Extending automation with data analytics and energy optimization using Python and modern IT tools.

Freelance Automation Engineer & IT/OT Integrator

I am an independent Automation Engineer with over 6 years of hands-on experience in commissioning production lines and single-purpose machines, primarily for Tier 1 automotive suppliers (e.g., Knorr-Bremse, Magna, Webasto).

My core added value lies in bridging the gap between traditional Operational Technology (OT) and modern Information Technology (IT). I don't just program PLCs and robots to make machines move; I design the architecture to securely extract, process, and visualize manufacturing data using modern DevOps principles.


CORE COMPETENCIES & TECH STACK:

  1. PLC Programming & Commissioning: Siemens Simatic S7 (TIA Portal), Beckhoff (TwinCAT 3). Full-cycle commissioning from writing logic to on-site deployment.
  2. Electrical Competence & Troubleshooting: Certified for independent work on live installations up to 1000V (Czech NV 194/2022 Sb. §7 / European BA5 equivalent). Able to safely open panels, measure, and troubleshoot on-site.
  3. Robotics & Vision: Industrial robot programming (Fanuc) and vision systems integration (Keyence).
  4. IT/OT Integration & Industrial IoT: Python development for machine communication (OPC UA, S7comm, MQTT, TCP/IP).
  5. DevOps & Infrastructure: Linux server administration, application containerization (Docker) at the edge, and deployment of IoT platforms (ThingsBoard, Apache Superset, Grafana) and SQL databases.


WHY WORK WITH ME?

  1. Single Point of Contact: You don't need to coordinate a PLC programmer and an IT server admin. I handle the entire ecosystem—from the sensor and robot movement up to the Docker container running your data dashboard.
  2. On-Site Leadership: I am used to "combat conditions" during commissioning. I can coordinate with mechanics and electricians, resolve hardware collisions, and drive the project to a successful handover under tight deadlines.
  3. Technical English: I am completely comfortable working with English technical documentation, writing code/comments in English, and handling the essential technical communication needed on-site to get the job done.


I am currently open to new B2B contracts (remote software development / IoT design + on-site commissioning across Europe). Let's connect and discuss how I can bring reliability and data transparency to your next automation project.
