About
Safer, more efficient and scalable infrastructures start with the right decisions and disciplined execution. Over 10+ years delivering results in civil engineering, building maintenance and facilities management. Every project follows the same logic: reduce risk, increase efficiency and extend asset life. ✔ Optimized corrective and preventive maintenance plans by 140% across operational units, increasing asset reliability and reducing emergency calls. ✔ Turned critical delay and rework scenarios into consistent 97% SLA performance, ensuring operational continuity. ✔ Structured technical and contractual improvements that delivered cost reductions of up to 15% without compromising quality. ✔ Led retrofit and expansion projects that generated direct productivity gains in distribution centers and industrial facilities. ✔ Strengthened safety and compliance standards, increasing adherence to ISO 9001 / 14001 / 45001 and FSSC 22000, with direct impact on risk reduction. My work is driven by a simple principle: anticipate before correcting. ✔ Daily application of planning, contract management and safety. ✔ Strong command of SAP, physical-financial schedules, CAPEX and OPEX management. ✔ Consistent performance in inspections, technical reports, project coordination, design compatibility and construction supervision. Education in Asset and Facilities Management from the University of Murcia, with specialization in Construction Management. My professional approach follows a continuous cycle: Reliability • Safety • Efficiency • Availability
