Hire the Best Mechanical Engineers
in Brazil

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.

Mechanical Engineer (PhD) specialized in thermal systems, energy efficiency and engineering modeling. I have several years of experience working with thermodynamics, heat transfer, energy systems and numerical simulation. My work focuses on analyzing and optimizing engineering systems using modeling, simulation and data analysis. I can support companies, researchers and engineering teams with: • Thermal and heat transfer analysis • Energy systems modeling and simulation • Thermodynamic and exergy analysis • Process and system optimization • Engineering calculations and technical reports • Python-based numerical modeling My background includes research and development in energy systems, heat recovery technologies and advanced engineering analysis. I have also worked in academic and industrial environments, developing technical studies, simulations and engineering solutions. If you need support with thermal systems, energy analysis, or engineering modeling, I would be glad to help.
