I use tools like SolidWorks, Fusion 360, and Onshape to deliver clean, efficient, and reliable CAD solutions. This is my full-time work, so I’m always available to support my clients with fast communication, consistent follow-up, and professional results. I take pride in building long-term relationships based on trust and quality. Currently offering reduced rates while growing my client base here on Upwork without compromising on standards. Let’s build something that works. ✅ What I can help you with: 3D modeling and mechanical design for enclosures, frames, and assemblies CAD for manufacturing: 3D printing, CNC machining, and sheet metal folding Design of waterproof housings and protective enclosures for industrial use Structural design of support brackets and internal hardware components Mechanical prototyping for refrigeration, automation, and heavy-duty systems Mounting and integration of electronics into mechanical assemblies Custom testing fixtures and product validation structures PCB mechanical layout integration (fitment, heat management, mounting) Functional jigs and guides for laser engraving and equipment alignment Development of early-stage hardware from concept to working prototype Full support for physical product development, from mechanical CAD to hands-on iteration

Are you looking for an engineer who can not only design your product but also communicate it clearly to manufacturers and customers? With over 5 years of experience and a Master’s degree in Mechanical Engineering, I bridge the gap between complex technical development and high-end visual communication. My background in Aeronautical and Mechanical engineering allows me to handle rigorous CAD projects, while my expertise in technical illustration ensures your documentation is professional and easy to understand. How can I help with your project? 📌 Mechanical Design & CAD: Expert 3D modeling. I specialize in Product Development, Sheet Metal design, and Design for Manufacturing (DFM) to ensure your parts are production-ready. 📌 Technical Illustration: I transform complex assemblies into clean, professional exploded views, 2D technical drawings, and instructional visuals for manuals. 📌 Product Documentation: From assembly instructions to technical reports and maintenance plans, I deliver clear, accurate documentation that reduces user error and manufacturing costs. 📌 R&D and Prototyping: Experience with international competitions (SAE AeroDesign, MotoStudent) and industrial products (Reclosers and electrical equipment). Technical Toolkit: 📌 Engineering: SolidWorks, AutoCAD, Mechanical Design, DFM. 📌 Visuals: Adobe Illustrator, Technical Sketching, Exploded Views. 📌 Languages: Fluent in English, Portuguese (Native), and Spanish. I am a "Rising Talent" on Upwork, which means I am fully committed to delivering exceptional quality to build long-term partnerships. I value clear communication, strict deadlines, and, above all, the functional success of your design. Let’s turn your technical concepts into reality.

Labview based instrumentation system for amperometric sensors characterization. Design, adjust and evaluation

Hi, I’m Saimon. I design systems and products that must work in the real world, under load, vibration, corrosion, pressure, heat, and continuous operation. Not just clean CAD models, but solutions that can be built, tested, and used in production. I’m new to Upwork, but I bring 20+ years of experience in R&D from industrial solutions and product design. 🔹 What I do • Mechanical design, from concept to CAD to production-ready • Product development and design improvement • Design for Manufacturing, DFM, and cost optimization • Structural, thermal, and vibration analysis, FEA • Engineering calculations and validation • Prototyping and real-world testing support • Electromechanical integration, mechanical + PCB + sensors Tools: SolidWorks | Fusion 360 | AutoCAD | Abaqus 🔹 What I deliver • Enclosures for electronics, 3D printed or injection-molded • Structural and sheet metal designs, fabrication-ready • Industrial machinery components and assemblies • Internal mechanisms, motion, guidance, interaction • Production-ready CAD + 2D drawings, GD&T and tolerances • DFM-optimized parts and assemblies • Thermal-aware designs, heat dissipation and airflow • Sealing systems, IP-rated and outdoor applications 🔹 Additional capability • Engineering data analysis using Excel and Python • Performance evaluation and system optimization • Basic predictive models for engineering applications • Design automation, CAD workflows and repetitive task reduction 🔹 How I approach projects I don’t start with CAD. I start with: • How the system will actually be used • Where it can fail • How loads and forces move through the design Then I build the solution around that. 🔹 Getting started Since I’m building my presence on Upwork, I’m open to starting with a small initial phase. This allows you to evaluate my work, speed, communication, and quality, before moving forward with a larger scope. 🔹 If you need to • Fix a design that isn’t working • Turn an idea into something manufacturable • Develop a prototype that performs in real conditions Let’s talk. ✉️ Send me a message, I’ll review your project and suggest the best way forward.
