What I'm looking for

I’m looking for a role where I can design and troubleshoot Rockwell-based industrial control systems, partner with operations to reduce downtime, and use Python/SQL analytics to improve reliability and visibility.

I’m an Industrial Automation Engineer with 8+ years of experience designing, supporting, troubleshooting, and maintaining industrial control systems. I specialize in Allen-Bradley / Rockwell Automation platforms, delivering reliable PLC, HMI, VFD, and industrial networking solutions across production environments to minimize downtime and improve system reliability.

I’m known for performing troubleshooting, root cause analysis, and system diagnostics across ControlLogix and CompactLogix PLCs, PanelView 5510 HMIs, and PowerFlex 520/525/40/750 drives, as well as Ethernet/IP and Stratix managed switches. I also use Python, Linux, and SQL for diagnostics, automation, and log analysis, and I’ve built projects like a Python-based industrial data acquisition system that integrates PLC data into SCADA dashboards to speed up troubleshooting and improve visibility.
