I help non-technical founders, inventors, and entrepreneurs turn rough ideas into functional, manufacturable mechanical prototypes.
If you have an idea, sketch, or concept but don’t know how to turn it into a real product that actually works — that’s where I come in.
I focus on function first:
Parts that assemble correctly
Designs that can be prototyped (3D printing / basic manufacturing)
Practical engineering decisions, not just “nice-looking” CAD
You don’t need to speak engineering. I translate your idea into a working mechanical solution.
Typical projects I work on:
Early-stage product prototypes
Mechanical parts that don’t fit or don’t work as expected
Improving manual or inefficient physical processes
Design fixes before manufacturing
What you get:
Clean, functional CAD models
Assembly-ready designs
Engineering thinking behind every decision
Clear communication, no unnecessary meetings
If your goal is a prototype that works in the real world, not just on screen I can help

I engineer high-precision sheet metal enclosures, NEMA/IP housings, and structural weldments engineered specifically for real-world production. I resolve CAD delays through custom DFM, delivering shop-ready packages that eliminate rework with zero staffing overhead.
Top Rated Plus Sheet Metal Designer & Metal Enclosure Design Engineer - 100% JSS, 215+ jobs, $122K+ earned, 91 five-star reviews, 10+ years designing NEMA/IP enclosures, racks & shipping-container structures.
▶THE ENGINEERING BOTTLENECK
Instead of theoretical CAD files that get delayed by fabricator RFIs, fabricator rework and scrap, I prioritize manufacturability from the first stroke. By applying shop-floor Design for Manufacturing (DFM) -including precise K-factor bend allowances, weld access rules, and GD&T tolerancing - I bridge the gap between engineering concepts and physical manufacturing.
▶HOW I WORK
This is a typical project design overview: Project Review → Mockup → Client Review → Detailed Design → Client Review → Final Delivery.
You receive complete, vendor-ready fabrication packages optimized for your fabricator’s specific tooling or platforms like Xometry, Protolabs, and SendCutSend.
This end-to-end process drives immediate cost reduction—eliminating shop-floor rework, cutting ECO cycles, avoiding material scrap, and delivering production results without the budget hit of internal staffing or software overhead.
▶TRANSPARENT PRICING & RETAINER OPTIONS
💠Fixed-Price Projects:
→ Custom Sheet Metal Parts packages start at $110 for ~2 Days delivery.
→ Custom Weldments and Assembly packages start at $330 for ~3-4 Days delivery.
→ Custom Parts Drawings packages start at $110 for ~2 Days delivery.
→ Custom Assembly Drawings packages start at $220 for ~3 Days delivery.
💠Hourly Monthly Retainers:
→ Under 40 hours/month: $55/hr.
→ 40–60 hours/month: $45/hr.
→ 60–80 hours/month: $35/hr.
→ Over 80 hours/month: $30/hr.
▶WHAT CLIENT SAYS & CASE STUDIES
💥"Luis was great to work with. He made sure he understood the project thoroughly before starting. During the process he gave thoughtful recommendations that made the finished product better. He provided complete materials and explanations at each milestone and was always open to suggestions and further discussions. I would not hesitate to use his services on future projects." - Logistics and Planning Event Manager.
💥Shipping Container Design - Designing custom localized non-welded Hooks to completely bypass structural inspection delays during transport.
💥"Luis' quality of work and level of detail and thoroughness was excellent - exactly what is needed for CAD activity. Using his experience and greater skill level, He was able to add unexpected detail and value to the drawings that our organization could not." - Engineering Manager, SKF USA.
▶CORE SERVICES
✅Custom Metal Enclosure Design: NEMA/IP-rated housings, Weatherproof, Ingress Protection Design (IP) electronic cabinets, cabinets, and racks engineered against your actual environmental and access requirements, so the design passes fabrication review the first time instead of bouncing back for rework.
✅Weldments & Structural Framing: Car racks conversions.
✅Shipping Container Designs: Footprints to match EU and US shipping pallets, Inspection bypass for forklift features and hoisting.
✅Sheet Metal & Flat Pattern Design: Bend allowances, laser layouts, and flat patterns dialed in to your fabricator's tooling, cutting factory cycle time and scrap from bad K-factors, CNC-ready DXF flat patterns, 2D shop drawings, and Technical Bill of Materials (BOM).
✅DFMA Review: I flag and fix the tolerance stack-ups, weld access issues, and assembly conflicts that generate fabricator RFIs before the package ever leaves my desk.
✅Fabrication-Ready Packages: SolidWorks/Inventor/Fusion models, STEP, DXF, BOMs, and fully dimensioned 2D drawings your vendor can quote and build from without a clarification call.
▶TECHNICAL CAPABILITIES | WHY WORK WITH ME
✅K-Factor Bending Optimization: Laser-cut DXF flat patterns optimized for CNC press brakes to prevent physical rework.
✅FEA Simulation: Linear static stress and load tests to target safety factors (1.5x to 2.0x) to simplify final structural certification.
✅MIG/TIG Frame Generator: Custom structural frames with real-time weldment cutlists.
✅GD&T ASME Y14.5 & ISO Fits: Precise tolerancing to eliminate workshop assembly clearance issues.
✅Lightweighting & DFM: Value engineering using geometric optimization to lower material costs.
✅Off-The-Shelf (OTS) Hardware Integration: Fastener and hardware routing (McMaster-Carr, Misumi, Wurth) with exact manufacturer part numbers.
✅Precise fabrication materials: CRS, A36/GR50, A500, AL 3003-H14, AL 6063, ABS, Silicone Rubber from suppliers like Ryerson.
