About

Electrical engineer specialized in substation design and industrial electrical installations, with extensive hands-on experience in MV/HV projects. I turn sketches, functional schematics and single-line diagrams into clean, accurate, workshop-ready documentation — and I also design complete panel and multi-panel systems from scratch: developed schematics, panel front layouts, internal and external wiring, interconnections, cable schedules, BOM and as-built documentation. Consistent, standards-based work (IEC), delivered in DWG, PDF and DXF. Fast turnaround, clear communication, available in English and Spanish. NDA-friendly.
