Hire the Best Mechanical Designers
in Brazil

Hi, I'm a mechanical engineer, product development specialist and founder of Appex Engenharia. I offer you complete projects from concept to ready to manufacture; structural and feasibility analysis to ensure safety and efficiency; support in innovation and design improvements, balancing cost, function, and aesthetics I dive deep into each client’s needs before proposing solutions regarding clear communication and realistic deadlines. Feel free to send me a message!

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.

I am a Mechanical Engineer with extensive experience in the metalworking industry, working from shop-floor operations to mechanical design and production management. I can help with mechanical drafting, metal structure design, manufacturing planning, and practical solutions aligned with real production processes. - Experience in mechanical drafting and design for laser cutting, bending, and sheet metal parts - Strong hands-on background in fabrication: cutting and bending, layout, welding, assembly, and boilerwork - Experience as Production Leader and Production Manager, including PPC, scheduling, and material planning - Cost estimation, technical quoting, and direct client support - Solid understanding of industrial processes and fast adaptation to new tools

I specialize in converting STEP files into clean, fully parametric SolidWorks models and creating precise 2D manufacturing drawings based on real production standards. My focus is to deliver models that are not only accurate, but also fully usable for manufacturing. I can help with: – STEP to SolidWorks conversion (feature-based models) – 2D manufacturing drawings (PDF, DWG, DXF) – Sheet metal design (flat patterns, bend details, K-factor) – Design adjustments and modifications I have hands-on experience with real production processes, including machining and sheet metal fabrication, which allows me to create practical and efficient designs. If you need clean, organized, and manufacturing-ready CAD work, I’m ready to help.

I am a Mechanical Project Designer with over four years of hands-on industry experience specializing in heavy fabrication, sheet metal, and complex parametric assemblies. I do not just draft 3D models; I design for manufacturability (DFM), ensuring that every assembly is structurally sound, stable for automation, and ready for the shop floor. Bridging the gap between engineering concepts and CNC/fabrication reality, I build intelligent, automation-ready CAD models using Top-Down (Skeleton) methodologies. This ensures extreme stability when dimensions or parameters change. Driven by a strong mindset of continuous improvement, I am always expanding my technical toolkit. I am currently advancing my programming skills (including Python and API automation) to develop even more powerful, software-driven CAD solutions. Additionally, I am continuously refining my Japanese language proficiency to broaden my ability to collaborate on high-tech international engineering projects. Core Competencies: Advanced 3D Modeling: Autodesk Inventor (Expert), SolidWorks. Parametric & Automated CAD: Skeleton modeling, rigorous User Parameters structuring, and API-ready model trees. Heavy Fabrication & Weldments: Structural frames (SHS/RHS), industrial equipment, hoppers, and custom enclosures. Manufacturing Documentation: Comprehensive 2D technical drawings (IDW/DWG), accurate BOMs, cut lists, weld symbols, and GD&T (ISO/DIN standards). Sheet Metal Design: Precision flat patterns, bend allowances, and CNC routing constraints. Continuous Development: CAD scripting for engineering automation and advanced Japanese language studies. Whether you need to build a robust standard parts library, design a custom industrial machine from scratch, or structure a parametric assembly for your software API, I deliver clean, precise, and highly organized engineering packages. Let's build something that works flawlessly from the screen to the factory floor.

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.
