Hire the Best Mechanical Engineers
in Spain

Hi, I'm Salvador. I help companies, startups, and inventors transform ideas into manufacturable products. Every design I create is developed with engineering in mind—not just appearance. I focus on functionality, manufacturability, cost optimization, and reliability from the very beginning. With over 6 years of experience, I can support your project from concept to production using SolidWorks, CATIA, Fusion 360, and AutoCAD. Whether you need a 3D model, a complete mechanical assembly, manufacturing drawings, FEA simulations, CNC programming, or realistic product renderings, I can help. My goal is simple: deliver designs that work in the workshop, not only on the screen.

I bridge the gap between digital design and physical reality. I help you turn ambitious concepts into precise, production-ready CAD — designed for manufacturing and backed by photorealistic visualization. As a BSc Mechanical Engineer with 74 completed projects, a 93% Job Success Score, and Top Rated status, I handle the full pipeline: concept → CAD → DFM → technical drawings → renders. What I deliver: Mechanical Design & Structural Assemblies: Robotics, mechanisms, brackets, and load-bearing components designed for real-world use. Full-Cycle Product Development: From initial concept to mass manufacturing. I manage the entire pipeline. Design for Manufacturing (DFM): CNC machining, injection molding, and 3D printing. I design what can actually be produced, not just pretty CAD. Technical Drawings & Production Documentation: GD&T, tolerancing, BOMs, and assembly instructions. Factory-ready from day one. Photorealistic Rendering & Product Visualization: Present your product before anything is manufactured. 1,193+ renders delivered. I cover the entire pipeline myself. You don't hire a CAD modeler, then a DFM specialist, then a renderer. You get all of it in one engagement — no communication gaps and consistent design intent from concept to production. Primary Engineering Stack: Fusion 360, SolidWorks, AutoCAD, ANSYS, Blender, 3ds Max + V-Ray, Rhinoceros 3D, MATLAB. Fluent in English, Spanish, and Lithuanian. Fast response times, and work starts the same day. Send me a message and let's discuss your project.

Are you looking to develop a complex mechanical product without costly design mistakes, validation delays, or regulatory bottlenecks? With over 24 years of hands-on experience in Mechanical Engineering and R&D Project Management—specifically within the ultra-strict Pharmaceutical, Life Sciences, and Machinery sectors—I don't just model parts; I deliver reliable, market-ready, and compliant industrial systems. As a Top Rated engineer with a 100% Job Success Score, I bring the rigorous methodology of high-precision regulated industries directly to your project. I bridge the gap between high-level R&D strategy and hands-on mechanical execution, ensuring every risk is mitigated before manufacturing. ⚙️ HOW I ADD VALUE TO YOUR PROJECT: R&D Project Management: Turning complex ideas into industrialized reality. Expert in leading cross-functional international teams, managing timelines (MS Project, Jira), and passing strict quality gates. Risk Mitigation & Reliability: Expert in FMEA (Failure Mode and Effect Analysis). I design with strict validation protocols (GMP standards) so your product complies with global regulations from day one. Advanced Mechanical Development: Solid expertise in thermal transfer, industrial refrigeration systems, cleanroom environments, automation, robotics, and ATEX standards. DFM / DFA Expertise: Optimizing designs for cost-effective production. Seamless fit in 3D, flawless prototype function, and ready for CNC, sheet metal, welding, or casting. 📈 PROVEN TRACK RECORD (From Concept to Market): Pharma & BioTech Innovation: Led R&D projects for automated robotic handling in autoclaves, portable sterilization units (VHP), and wireless sensors for sublimation monitoring. Global Operations: Co-led international R&D teams across Europe and managed prototyping/industrialization transfers directly with manufacturing plants in Shanghai. Heavy Industry & Automation: Over a decade designing custom machinery, sheet metal systems, and complex transport/FMS conveyor lines. 💻 TECHNICAL TOOLKIT: CAD: Expert in SolidWorks and AutoCAD Engineering Analysis: FEA simulation, advanced structural & kinematic analysis, and mechanical calculations. If you need a senior engineering partner who understands strict timelines, risk analysis, and how to execute flawless validation-ready documentation, let’s talk. Click the "Message" or "Invite" button, and let's discuss how to secure your next product innovation.
