🔧 Experienced Mechanical and Product Design Engineer with a strong background in 3D modeling, CAD/CAM development, and end-to-end product design. Over the years, I have worked across a wide range of industries — from industrial machinery and consumer products to automotive components and custom mechanical assemblies — delivering precise, manufacturable, and innovative design solutions that meet both functional and aesthetic requirements. My core expertise lies in SolidWorks, where I design complex 3D models, detailed part drawings, and full assembly structures with a focus on design intent, parametric modeling, and design for manufacturability (DFM). I am highly proficient in creating production-ready technical drawings with GD&T annotations, bill of materials (BOM), and revision-controlled documentation that meets industry standards and client specifications. ⚙️ CAD/CAM & Manufacturing My CAD/CAM experience bridges the gap between design and production. I develop toolpaths, machining strategies, and CNC programs for milling, turning, and multi-axis machining operations. I work closely with manufacturing teams to optimize part geometry for machinability, reduce material waste, and shorten production lead times. Whether working with metals, plastics, or composites, I understand how material properties and machining constraints influence design decisions from day one. 🖥️ 3D Modeling & Prototyping I specialize in surface modeling, solid modeling, and hybrid design approaches to tackle both organic shapes and highly precise mechanical components. My 3D modeling workflow supports rapid prototyping — I prepare files for 3D printing (FDM, SLA, SLS) and coordinate with prototype shops to validate designs before committing to full production tooling. This iterative approach saves clients time and money while ensuring the final product performs exactly as intended. 💡 Product Development & Design Process I am experienced in taking products from concept to completion. Starting with client briefs, sketches, or reference samples, I develop initial concept models, refine geometry based on feedback, conduct basic finite element analysis (FEA) checks for structural integrity, and prepare final design packages for manufacturing. I understand the importance of clear communication throughout the design process and provide clients with regular updates, renders, and documentation at each milestone. 🔍 Reverse Engineering I have extensive experience in reverse engineering existing parts and assemblies — using physical measurements, calipers, CMM data, or 3D scan data to recreate accurate digital models. This is especially valuable for legacy parts, obsolete components, or situations where original CAD data is unavailable. The result is a clean, parametric SolidWorks model ready for modification, improvement, or direct manufacturing. 🏭 Industries & Applications Throughout my career I have delivered design solutions across a broad spectrum of industries including: 🔩 Industrial machinery and equipment 🚗 Automotive and motorsport components 📱 Consumer electronics enclosures and housings 🏥 Medical device and laboratory equipment 🚜 Agricultural and heavy equipment parts 🪑 Furniture, fixtures, and custom fabrication ✈️ Aerospace structural and interior components 🤝 Why Work With Me? I take pride in delivering clean, accurate, and well-documented designs on time. I approach every project with attention to detail, engineering discipline, and a commitment to understanding each client's unique requirements. I do not just model what is asked — I think critically about how parts will be manufactured, assembled, and used in the real world, and I flag potential issues before they become costly problems. I am comfortable working independently or as part of a larger engineering team, adapting to different workflows, file formats, and collaboration tools as needed. Communication is a priority — clients always know where their project stands. Whether you need a single custom part modeled, a full product designed from scratch, a legacy component reverse engineered, or CNC toolpaths developed for production, I bring the technical skills and professional discipline to get it done right. 💪 Let's connect and discuss how I can add value to your next project. 🚀 ------------------------------------------------------------------- ✅ Skills at a Glance: SolidWorks · CAD/CAM · 3D Modeling · Surface Modeling · GD&T · Technical Drawings · CNC Programming · Reverse Engineering · FEA · DFM · Rapid Prototyping · 3D Printing · BOM & Documentation · Product Development · Assembly Design
