Work History
RELIABILITY ENGINEER 2
FREEPORT-MCMORAN
Morenci, AZ
05.2025 - Current
- Severe vibration in Crusher 3 was resolved through root cause analysis that identified broken bolts and improper torque. Inspection plan based on manufacturing recommendations led to replacement of broken 6-foot bolts. Potential damage to the $50 million structure was avoided through proactive corrective action.
- Performed RCFA on critical assets (Crusher 2 & 3, gearboxes, motors, fluid couplings, zero speed & vega sensors, tilt probes, conveyors, feeders). Implemented corrective actions to eliminate failures and improve long-term reliability.
- Led redesign of conveyor chutes based on material flow analysis; implemented new chute geometries and magnetic liners to prevent blockages. This eliminated 25 hours/week of chute unplugging, resulting in an estimated $3,750,000/Week in production savings.
- Coordinated outage efforts, ensuring work readiness, Gantt chart creation, material availability, and training compliance, which streamlined execution and minimized delays.
- Collaborated with electrical team to optimize conveyor velocity and reduce material spillage, saving over 40 labor hours/month previously lost to cleaning and stoppages.
- Supported belt splicing and emergency belt replacements, helping reduce unplanned downtime and restore production continuity.
- Managed installation of new motors, shaft wiring, MFA sensors, and internal logic reprogramming during 11-day crusher 2 head shaft replacement.
- Owned end-to-end dust control modernization by replacing broken dust pipes and upgrading MFA sensors, ensuring improved dust collector performance and enabling continued full remote operation from control room.
- Analyzed equipment failure trends to improve maintenance strategies and asset reliability.
- Reviewed preventive and predictive maintenance plans for rotating and fixed plant assets.
MECHANICAL ENGINEER 1 & 2
FREEPORT-MCMORAN
Morenci, AZ
10.2021 - 05.2025
- Managed engineering projects to enhance and maintain critical systems, including crushers, jib cranes, chutes, dust collectors, and head pulley platforms, resulting in improved safety and operational performance through effective design, procurement, and implementation.
- Collaborated with operations, maintenance, and electrical teams to resolve systemic issues on the Crush & Convey system—covering tasks such as crusher gapping, sensor calibration, and replacement of motors, pumps, gearboxes, belts, pulleys, and idlers.
- Performed a comprehensive PM gap analysis that reduced job duration from 26 to 12 hours by identifying inefficiencies related to labor delays, contractor coordination, and resource planning.
- Authored and standardized SOPs for critical maintenance tasks, including surge bin liner replacement, apron feeder rebuilds, and mantle/concave liner installation to ensure repeatability and improve safety.
- Conducted comprehensive PM gap analysis, identifying inefficiencies in labor delays, contractor coordination, and resource planning, which reduced job duration from 26 to 12 hours.
- Mentored junior engineers in design principles and best practices, fostering a culture of knowledge-sharing and continuous learning among team members.
- Evaluated rotating equipment performance indicators and condition signals to inform maintenance planning, contributing to a successful 35% downtime reduction project and reduced unplanned downtime.
