• Led the development of the Maintenance Planning and Control department, structuring processes and workflows aligned with operations and engineering. • Created and monitored maintenance KPIs, defined planning and scheduling metrics, developed detailed schedules using MS Project, tracked costs, and managed maintenance contracts. • Registered and structured equipment data within the IBM Maximo CMMS system. • Created and managed preventive and corrective maintenance plans within IBM Maximo, ensuring compliance and traceability. • Participated in the organization and preparation of minor maintenance shutdowns, focusing on schedule, resource planning, and safety. • Internal auditor for ISO 9001, ISO 14001, and ISO 45001, supporting alignment with quality, environmental, and occupational safety standards. Reporting directly to Coordinator: Luis Eduardo Tavares.

• Acted during the startup phase of UTE Pecém I (EDP/MPX consortium), participating in the complete structuring of the plant’s maintenance system from the ground up. • Responsible for the technical registration of all equipment, creation of preventive maintenance plans, spare parts structuring, installation location mapping, and asset hierarchy setup. • Led the implementation of IBM Maximo CMMS as a key user, contributing to system design, workflow creation, data loading, testing, and technical team training. • Participated in the development of the Maintenance Planning department, helping define scope, workflows, and integration with operations and supply chain. • Supported the contracting and management of framework (umbrella) agreements for mechanical services, preventive and corrective maintenance execution. • Followed up on scheduled maintenance shutdowns and supported the warranty management process for major equipment and systems. • Supported the construction and commissioning of two thermal power units, including Doosan Babcock subcritical boilers, Siemens 360 MW turbogenerators, FGD systems, coal mills, axial fans, and Siwertell ship unloaders. Direct managers: Eng. Eduardo Piropo and Eng. Paulo Araújo.

• Oversaw master maintenance planning and scheduling. • Prepared weekly performance indicator reports. • Managed maintenance plans using the DATASUL system. • Ensured compliance with legal and regulatory maintenance requirements. Reported directly to Coordinator Rafael Oliveira and Anderson Maciel.

• Led mechanical maintenance team including welding, piping, and refrigeration (7 team members). • Managed backlog, procurement, and productivity control. • Performed maintenance on reactors, tanks, isocontainers, pumps, diesel generators, air compressors, PSV valves, labeling and filling machines, conveyors, and electric hoists. • Developed and implemented failure analysis processes. • Implemented deviation treatment system to reduce failures, downtime, and maintenance costs. Reported directly to Supervisor: Silvio Vitorino.

• Mechanical lead for the Natural Gas Furnace (Bendoti – 30T/h) and Utilities in the Rolling Mill area. • Managed departmental purchase requisitions. • Performed preventive, corrective, and predictive maintenance on rotating equipment, pumps, radial fans, 30/45t overhead cranes, cooling towers, WTP, hydraulic/pneumatic systems, air compressors, cutting & bending systems, descaling systems, and cooling beds. • Conducted failure analysis using MASP methodology (Problem Solving and Root Cause Analysis). • Reviewed maintenance plans in SAP PM. • Achieved a reduction in furnace downtime from 9.3 h/month to 11 min/month — saving BRL 284K/month or BRL 3.4 million/year in lost profit (51x reduction). Direct manager: Eng. Heleno Peres Girão.
