I’m Sai Krishna Manthena, an Automation & Controls Engineer with 4+ years of experience delivering industrial automation and manufacturing solutions. My background combines electrical and controls engineering with software, data, and industrial IoT, allowing me to work across both OT and IT environments. In my current role at Paton Engineers & Constructors in Texas, I work on industrial automation projects for customers, designing and programming Allen-Bradley ControlLogix PLC systems, developing FactoryTalk View SE SCADA applications, integrating PowerFlex VFDs and servo-driven equipment, troubleshooting EtherNet/IP and OPC UA communications, and supporting FAT, SAT, commissioning, and startup. I have contributed to six industrial automation projects and helped deliver four major projects on schedule. My work has reduced commissioning time by 25%, startup tuning time by 35%, and commissioning delays by 40%. Previously, I worked as a Controls and Systems Engineer at Honda in Hyderabad, India, where I programmed and commissioned Siemens S7-1200/1500 PLCs using TIA Portal for production equipment, conveyor systems, and manufacturing automation. I also worked on electrical schematics and panel modifications, integrated more than 150 field devices, configured PROFINET and PROFIBUS networks, and provided production troubleshooting and control-system optimization. One of my key accomplishments was modernizing legacy relay-based control systems, resulting in approximately 12% lower power consumption and improved system reliability. One project that particularly demonstrates my ability to combine automation and software was a smart warehouse sortation system, where I integrated Allen-Bradley PLCs with a Python-based sorting algorithm through OPC UA. The solution reduced sorting errors by 65% and supported throughput of up to 1,500 units per hour. What makes me stand out is my ability to bridge traditional industrial automation with modern software and data technologies. Along with PLC, SCADA, electrical controls, motion control, instrumentation, and industrial networking, I have experience with Python, SQL, REST APIs, AWS IoT Core, Docker, MQTT, and edge computing. I also hold an M.S. in Computer Science, an Ignition Core Certification, Rockwell Studio 5000/ControlLogix certifications, Siemens TIA Portal training, and ISA CCST Level I certification. I bring a combination of hands-on controls engineering, software knowledge, customer-focused problem solving, and measurable project results. My goal is to help clients build safer, more reliable, connected, and efficient automation systems while continuing to take on challenging engineering problems.
