• Managed contractual KPIs through Power BI dashboards, ensuring operational compliance and data-driven decision-making across PRONATEL broadband projects in 4 regions.
• Automated implementation reports and field documentation using Python, reducing processing times by 64% and improving traceability for 1,776 beneficiary entities in Áncash and La Libertad.
• Planned and dimensioned remediation actions for non-compliances identified through technical inspection protocols across telecommunications infrastructure (AC/DC power, HVAC, security, networking, and microwave systems).
• Led the resolution of 100% of critical non-compliances across 320 nodes under PRONATEL / OCI supervision.
• Prepared technical files, protocols, and operational reports for 454 optical nodes and 1,040 radio nodes, using Java and VBA scripts to automate data validation and structuring.

Mechanical & Electrical Engineer at BITEL (VIETTEL PERU S.A.C.) (2022-06 – 2023-11)

• Led and supervised on-site commissioning of power systems (rectifiers, ATS, generators) at new sites – executing startup testing and energization checklists – reducing critical incidents to zero.
• Executed a comprehensive energy efficiency plan, reducing electrical consumption at nodes by 30%.
• Monitored alarms and performed topological analysis during massive power outages, identifying cascading impact and optimizing 440 backup systems through strategic battery redistribution.
• Diagnosed and resolved power incidents at BTS sites (AC/DC, ATS, rectifiers, batteries, generators), executing the ATS test plan and ensuring optimal operation across 94 critical nodes in 14 regions.
• Planned and coordinated activation of 78 new low-voltage electrical supplies, ensuring technical feasibility, regulatory compliance, and timely energization.
• Dimensioned DC power systems for 519 new low-voltage antennas, 4 medium-voltage antennas, and 36 solar-powered sites; supported installation and configuration of rectifiers, generators, and HVAC equipment at 290 new sites.

Electrical Maintenance Intern at SOUTHERN PERU COPPER CORPORATION (2021-05 – 2021-12)

• Supervised electrical work during the overhaul of the L-2350 LeTourneau front-end loader, reducing execution time by 40% through efficient planning, parallel execution, and optimal materials management.
• Participated in planning and supervision of electrical maintenance (preventive, predictive, corrective), including troubleshooting and event logging on critical mining equipment: Komatsu electric haul trucks, shovels, drills, and P&H electric front-end loaders – contributing to plant operational continuity.
• Managed mining maintenance in the concentrator plant and mine using SAP PM (ERP) software, creating and administering over 90 records including work orders, failure notifications, purchase requisitions, reservations, and routing sheets.
• Prepared monthly reports under Integrated Management Systems (IMS), covering electrical rooms, MCC, PowerFlex7000/755 variable frequency drives, and crushing, HPGR, grinding, flotation, filtering, and tailings equipment.
• Updated over 20 technical documents (work procedures, electrical drawings, and test protocols) in accordance with IEEE standards, strengthening standardization and operational reliability.

Process Engineering Intern at PETROPERU S.A. (2020-01 – 2020-05)

• Participated in the implementation and supervision of industrial instrumentation and cathodic protection systems across 14 storage tanks, ensuring asset integrity and corrosion control.
• Supported technical and field engineering supervision for the expansion of 2 electrical substations, verifying compliance with technical specifications and safety standards.
• Supported supervision of automation system implementation for product dispatch, ensuring correct field execution and distribution process efficiency.
