Automation Systems Engineer (P.E.) specializing in capital equipment, robotics, and multi-station automation systems. Brought in by companies before system build—or when systems aren’t performing—to define architecture, reduce risk, and ensure real-world performance. Most of my engagements begin with a paid engineering consultation to review system architecture, risks, and manufacturability before fabrication. This early review helps identify design issues, simplify system complexity, and avoid costly rework during build and integration. I typically work on: automation system architecture and layout definition robotic cells and machine tending capital equipment design troubleshooting underperforming automation systems I am frequently engaged prior to system build to reduce technical risk and improve performance outcomes. I am a licensed Professional Mechanical Engineer (P.E.) with over 20 years of experience designing production-ready industrial machinery, automation systems, and complex assemblies, primarily using SolidWorks. Most of my engagements begin with a paid engineering consultation to review the problem, risks, and system architecture before moving into design work. I work with clients who need more than drawings—they need sound engineering judgment, manufacturable designs, and systems that perform reliably in the real world. My background spans concept development through detailed design, vendor coordination, fabrication, installation, and production support. I have led and contributed to high-impact equipment programs with leading machine builders and industrial organizations, including ATS Automation, ACRO Automation, DISA Group, Ixmation, and ITW. My work has supported industries ranging from automated assembly and materials handling to foundry systems, robotics, and custom machinery. What I bring to projects Senior-level mechanical engineering judgment and design ownership Production-focused SolidWorks design (assemblies, mechanisms, tooling, layouts) Strong emphasis on manufacturability, tolerances, and serviceability Experience working directly with fabricators, integrators, and global vendors Ability to identify risks early and simplify complex systems Multiple issued patents in machinery and automation technologies I have worked with clients, customers, and suppliers across the United States, Europe, and Asia, and I am comfortable collaborating remotely or on-site as needed. I am often engaged not just to design equipment, but to help clients think through architecture, tradeoffs, and long-term scalability. Education & Credentials B.S. Mechanical Engineering & MBA – University of Notre Dame M.S. Manufacturing Engineering – Western Michigan University Registered Professional Engineer (P.E.) Adjunct instructor for senior mechanical engineering design projects - Benedictine College Client & Colleague Feedback “Paul is a goal-oriented engineer who brings insight and a tremendous variety of engineering talent and experience to any project. He is an out-of-the-box thinker who stays focused on strategic objectives.” “Paul solved our problems in a highly creative and inspiring way. I recommend him without any reservation.” “Paul brought structure, discipline, and clarity to an unorganized engineering group and left a lasting positive impact.” “Paul is an outstanding design engineer whose work became industry-standard machinery.” If you’re looking for a senior mechanical engineer who can own technical decisions, reduce risk, and deliver practical, production-ready solutions, I’d be glad to discuss your project.

Experienced controls engineer with years in the automation industry. • Programming for Allen Bradley, AB, IDEC, Siemens, Redlion, Automation Direct PLCs, Codesys, Others • Wiring Diagrams • IEC Standard Panel Design • HMI Design • System Upgrades • IoT SCADA • Commissioning Support • Troubleshooting • Budget or High Performance Systems • UL Compliance

I graduated with honors from Southern Polytechnic State University with a bachelor's degree in Mechatronics Engineering. I have worked professionally as a control systems engineer for over a decade, mainly working with clients in the water and waste water treatment industry. Over this time, I have gained profound experience using all of the devices available from most of the big name PLC and SCADA software manufacturers, such as Allen-Bradley, Schneider Electric, Automation Direct, Wonderware, Maple Systems, etc. I have also gained experience in a variety of other areas, including performing electrical wiring, submitting design documents, managing projects, designing CAD drawings, configuring applications, designing and troubleshooting network configurations, creating HMI's, and much more.

I help businesses turn manual processes into automated AI-powered workflows. My work combines AI development, software integration, automation, and engineering expertise to build practical solutions that save time, reduce repetitive work, and improve business processes. I can help with: AI agents and intelligent automation LLM integrations and AI-powered applications API integrations and workflow automation Custom AI tools and internal business applications Data processing and automation AI chatbots and document-processing systems CRM and business-system integrations Python-based automation and backend development Custom software and technical integrations Engineering and industrial automation solutions My engineering background gives me a particularly strong ability to work on technical, engineering, industrial, and data-intensive applications where understanding the underlying business or technical process is just as important as writing the software. I approach projects from an end-to-end perspective: understanding the workflow, identifying where AI or automation provides real value, designing the solution, and delivering a working implementation. I also have extensive experience working with clients on Upwork and understand how to communicate requirements clearly, manage deliverables, and deliver projects reliably. If you have a repetitive process, disconnected systems, or a business workflow that you think could be improved with AI, I can help turn it into a practical, production-ready solution.
