I'm Dimitrios Tsiolchas — a Senior Automation Engineer based in Thessaloniki — Greece, available for freelance and contract work across the EU. Finding an engineer who can handle the full project lifecycle — from concept to commissioning — without surprises is rare. That is exactly what I deliver.
With 13.5+ years across PLC, HMI, SCADA, Robotics & Advanced Motion Control, I take full ownership of the entire engineering process — design, integration, programming and FAT/SAT commissioning. I don't hand off problems. I solve them.

It was a great experience for me to work together with Dimitrios and I learned a lot during our cooperation.
Dimitrios is a passionate, yet a self-motivated senior engineer as well, who is specialized in Control and Automation Application Projects, while during the time we jointly collaborated, he attained expertise in the field of Automated Wastewater Treatment Plants.
Key strengths, which I distinguish, include, a dynamic cognitive background, proven competency of effective communication, as well as fast adaptation in diverse technical business environments.
Most importantly, not only he demonstrates in-depth engineering experience in large scale Automation Projects, in programming of PLC and SCADA, in Networking and FieldBus Communications and in VFD applications, but he effectively administers exploitation of available resources and creative problem solving, through abstract, lateral and concrete thinking, as well.
I'm looking forward collaborating with him on a future project!

Dimitrios is a bright, innovative and hard-working automation engineer. I have been his teacher in digital electronics and also supervised his final year project. He aced both my undergraduate courses, while during his project he demonstrated his ability to take an engineering challenge from a paper napkin sketch to a fully tested, documented and working electronics system. During the project he also proved that he can generate and fulfill design requirements, prepare a realistic Gantt chart and stick to its deadlines, foresee future problems and take action ahead of time, as well as take mishaps in stride. He is a well mannered team player and collaborating with him has been a joy.
From initial concept — including Applied R&D — to complete PLC, HMI, SCADA, Robotics & Motion programming and system integration using Mitsubishi MELSEC & Siemens SIMATIC — platforms I have in-depth mastery of, meaning zero know-how overhead and immediate project momentum. I deliver robust, maintainable solutions that are ready for production from day one.
Full integration of FANUC and Mitsubishi MELFA industrial robots with high-performance synchronized motion systems (MELSERVO, closed-loop stepper, VFD). Specialized in robotic welding, custom palletizing, machine tending, pick-and-place, and complex multi-axis applications.
Complete factory and site acceptance testing, full commissioning, troubleshooting, and ongoing technical support — both on-site and remote. I ensure zero surprises during start-up and fast resolution of any production issues.
Expert consulting for complex automation projects, leveraging my deep Mitsubishi expertise to optimize & upgrade both new as well as obsolete systems and processes. I design SIL3 safety systems, deliver complete turnkey integration between machinery, robotics, and higher-level systems, and provide strategic planning for efficiency and scalability.
Standalone services for specific automation elements, including custom configuration, programming, and commissioning of PLC, HMI, SCADA, Robotics & Motion systems. Ideal for targeted developments, upgrades or troubleshooting, with full support for Mitsubishi, Siemens, FANUC and related technologies.
