I will design electrical panels and substation schematics
Subgrids
About this gig
Electrical engineering, not just drafting.
I'm an electrical engineer specialized in substation design and industrial installations. I turn your sketches, functional schematics or single-line diagrams into clean, accurate, workshop-ready documentation.
What I offer:
BASIC CAD Drafting: your hand-drawn sketches, markups or as-built redlines converted into clean AutoCAD drawings, delivered in PDF.
STANDARD Panel Design: complete electrical panel/switchboard design from your technical specifications and single-line diagram. I generate the functional schematic, panel front layout and bill of materials.
PREMIUM Substation Package: multi-panel projects from your single-line diagrams: developed schematics, internal and external wiring, interconnections, cable schedules, BOM and as-built documentation.
Deliverables: DWG, PDF and DXF. Source files included in Standard and Premium.
Why work with me:
- Real hands-on experience in substation engineering (MV/HV)
- Consistent, standards-based documentation
- Fast turnaround and clear communication
- Work available in English and Spanish
- NDA available upon request

My Portfolio
FAQ
What do you need from me to start?
For drafting: your sketches, scans or marked-up drawings (PDF or photos). For panel design: your technical specifications and single-line diagram. Any format works — PDF, DWG, or even a clear photo of a hand-drawn sketch.
Which software and file formats do you work with?
I work in AutoCAD and excel. Deliverables are provided in PDF, DWG and DXF. Source files (DWG) are included in the Standard and Premium packages, and available as an extra in Basic.
Do you follow any specific standards?
Yes. My documentation follows IEC standards and consistent industry drafting practices. If your company uses its own templates, title blocks or symbol libraries, I can adapt to them — just share them when placing the order.
Is my project information confidential?
Absolutely. Your drawings and project data are never shared or reused. I'm happy to sign an NDA before you send any documentation.
My project doesn't fit any of the packages. Can you still help?
Most likely, yes. Message me with a short description of your scope and I'll prepare a custom offer with pricing and delivery time tailored to your project.
