I move designs from intent through execution. That means developing the geometry, assemblies, drawings, details, specifications, tolerances, materials, processes, and configuration needed for a design to survive contact with fabrication, construction, inspection, purchasing, and production. My background spans California architecture and development, aerostructures, composites, mechanical design, and manufacturing. I work with DFM/DFA/DFx, GD&T, tolerance stacks, BOM and configuration structure, quality, supplier constraints, and standards-based documentation. I approach the work with the downstream consequences in mind: how something will be made, bought, assembled, inspected, changed, and represented in MRP/ERP systems. Where specialist engineering is required, I know what needs to be surfaced, how to define the problem, and when to bring in the responsible engineer. For architecture, I provide senior design and documentation support to architects and engineers on substantial residential projects, with project scale generally equivalent to $1M+ construction in higher-cost markets. My role is not simply to draw what is given to me, but to help carry the design through to a clear, coordinated, buildable set of documents.

Architect and BIM professional with 13+ years of experience across industrial, energy, laboratory and residential projects. Currently designing and modelling complete HVAC systems for industrial and CCGT (combined-cycle gas turbine) facilities in Revit, with strong background in multidisciplinary coordination, clash detection and model QA/QC using Revit and Navisworks. What sets me apart: hands-on Dynamo and Python automation. I completed 65 hours of dedicated Dynamo/Python training and built working tools that automate repetitive BIM tasks - automatic parameter tagging and numbering, rule-based device coding, and BIM data QA/QC scripts that flag missing or out-of-range values before they become model errors. I can help with: HVAC/MEP BIM modelling and coordination, Revit family creation and standards, multidisciplinary clash detection, and custom Dynamo/Python scripts to automate repetitive Revit workflows (tagging, numbering, parameter checks, data extraction). Fluent in English (Cambridge FCE, B2) and native Spanish. Based in Madrid, available for remote work worldwide.

I make hardware happen in China. You have a product idea. You need someone who can actually build it – not just draw it, but mold it, assemble it, and ship it. That's what I do. Here's what makes me different: 🏭 FACTORY ACCESS My family runs an injection molding factory + tooling shop in Zhejiang, China. When you work with me, you're not hiring a freelancer – you're getting direct access to a production line. 📦 SMALL BATCHES WELCOME Need 500 units? Most factories won't even reply. I will. I handle prototyping ➔ mold making ➔ production ➔ shipping, all in one seamless workflow. 🔧 13 YEARS, 4 INDUSTRIES Over 13 years of heavy engineering experience across personal care (hair dryers, beauty devices), outdoor power equipment (lawn mowers), and children's ride-ons. If it has plastic parts and electronics, I've built it. WHAT I CAN DO FOR YOU: ✅ Full product development: sketch ➔ 3D design ➔ prototype ➔ tooling ➔ production ➔ delivery ✅ DFM analysis + mold design + competitive supplier quotes ✅ Small batch pilot production (500–5,000 units) with water resistance & fatigue testing ✅ Competitor teardown + cost analysis reports ✅ Factory audits and quality control in China ✅ Payment in USDT accepted HOW IT WORKS: 1. You share your idea (sketch, reference, STL – anything works). 2. I design for manufacturing + quote you the full cost. 3. You approve ➔ I make the mold ➔ run the production. 4. You receive finished products at your door. Let's talk about your project. Click the button and tell me what you're building. I'll respond within 24 hours.
