Automation Engineer Nestle Texas Aug 2025 – Sep 2026

• Modified PLC programs using Siemens TIA Portal and Allen -Bradley Studio 5000 to support equipment changes, sequencing improvements and control requirements during testing and commissioning

• Developed and updated HMI screens using WinCC and FactoryTalk View for equipment status, process values, alarms, operator controls, improving visibility into equipment operation and supporting faster troubleshooting.

• Troubleshot sensors, instrumentation and PLC I/O issues, reducing average fault -diagnosis time by ~15% through systematic signal tracing, I/O verification, field-device checks and control-logic analysis.

• Performed I/O checks and control-panel testing by verifying field wiring, PLC signals, relays, contactors and electrical drawings to ensure proper control-system functionality during project execution.

• Supported industrial communication between PLCs, HMIs and field devices using PROFINET/EtherNet /IP, troubleshooting connectivity and device communication issues to maintain ~95% communication availability

• Participated in FAT, SAT and commissioning activities, testing equipment sequences, alarms, interlocks and operator controls, identifying control issues during validation and supporting successful system handover.

• Worked with VFD-controlled motors to support speed control, start/stop operations and troubleshooting of drive- related faults, ensuring reliable motor operation during equipment testing and production.

• Maintained I/O lists, control drawings and commissioning documentation for multiple automation systems, ensuring accurate project records and reducing troubleshooting and documentation turnaround time by 10%. Automation Engineer L&T India Jun 2020 – Aug 2023

• Supported automation systems across manufacturing lines, contributing to a 10–15% reduction in unplanned equipment downtime through systematic controls troubleshooting, root-cause analysis and timely actions

• Troubleshot Allen-Bradley ControlLogix systems using Studio 5000, analyzing PLC I/O, alarms, control logic and equipment sequences to identify faults, restore equipment operation and reduce troubleshooting time.

• Supported HMI/SCADA systems across production assets, improving alarm visibility, equipment monitoring and operator response to equipment issues by reviewing process values, alarm conditions, equipment status

• Resolved communication issues between PLCs, HMIs, remote I/O and drives, troubleshooting network connections, device status and communication faults to reduce production interruptions by 15%

• Worked with maintenance, production and engineering teams on recurring equipment failures, contributing to a 15% reduction in repeat automation-related breakdowns through effective troubleshooting

• Participated in commissioning and startup of equipment upgrades, performing pre-startup I/O checks, sequence validation and testing to identify control issues early, reduce startup delays and support smooth handover.

• Supported continuous-improvement initiatives focused on automation reliability, contributing to improvement in overall equipment availability across supported production assets. EDUCATION
