Industrial Automation Engineer | PLC, SCADA | BAS | IT/OT | Industrial Networks | IIoT | VFD | MSc.

I am an Industrial Automation and Electronics Engineer with extensive hands-on experience in PLC-based control systems, SCADA/HMI, VFDs, industrial networks, instrumentation, machine automation, and electronic systems. I am currently expanding my traditional automation expertise into modern Web SCADA, IT/OT integration, Building Automation, and AI-assisted engineering. As part of this development, I am building and testing a web-based SCADA platform using Node.js/Express, REST APIs, PostgreSQL, OPC UA, MQTT, and Web HMI technologies. This work is helping me bridge OT systems with modern software architecture while maintaining a practical automation-engineering perspective. My automation experience includes PLC programming, SCADA, HMI, BAS/HVAC concepts, VFD commissioning and troubleshooting, and industrial communication protocols including PROFINET, EtherNet/IP, Modbus TCP, OPC UA, MQTT, and BACnet. I also bring a strong electronics and embedded-systems background, including hardware design, PCB and prototype development with Altium Designer, firmware development, and hands-on work with Raspberry Pi, Arduino, ESP32, and other microcontrollers. More recently, I have been exploring AI, LLMs, AI-assisted development, Python, APIs, and data-driven methods to improve engineering workflows such as documentation, troubleshooting, data analysis, and system integration. I see AI as an engineering tool that can improve productivity and decision-making—not as a replacement for engineering judgment. Throughout my career, I have worked with multidisciplinary teams of engineers, technicians, software developers, and project managers, and have led and mentored technical teams. I combine analytical problem-solving with practical implementation, commissioning, troubleshooting, and continuous learning.
