I’m Sanjay Karthik, a Mechanical Design and Simulation Engineer specializing in standards-compliant mechanical design, validation, and optimization for industrial systems across automotive, aerospace, heavy machinery, energy, and industrial sectors. I support engineering teams through design calculations, structural, thermal, and flow validation, FEA-driven optimization, and manufacturing-focused design, ensuring products are technically sound, compliant with EN / ISO / IS standards, and ready for production. My focus is on delivering validated engineering decisions—not just CAD models—helping clients reduce development risk, shorten design cycles, and move confidently toward manufacturing. ---------------------------------------------- 🔧 What I Help You Achieve 🔹 Validate engineering concepts before costly prototyping and testing 🔹 Reduce structural weight while maintaining required safety margins 🔹 Ensure compliance with ISO, EN, IS, DIN, and MIL engineering standards 🔹 Improve manufacturability, reliability, and overall system efficiency 🔹 Reduce physical prototyping through virtual simulation and engineering calculations ---------------------------------------------- 🛠 Core Engineering Design & Development Services ✅ Design Optimization: Multi-physics performance and compliance. ✅ End-to-End Design: Concept to production systems. ✅ DFM/DFA: Manufacturing-ready design. ✅ Reverse Engineering & Parametric Re-design for cost reduction. ✅ Advanced Simulation: FEA, CFD, NVH, and MBD validation. ---------------------------------------------- 🏭 Multi-Industry Experience 🔸 Automotive subsystems and load-bearing structural components 🔸 Aerospace ground support and auxiliary equipment 🔸 Heavy machinery and material handling systems 🔸 Energy, power, and thermal engineering systems 🔸 Industrial and defense auxiliary equipment (non-ordinance) ---------------------------------------------- 📊 Why Choose to Work With Me ✔ Engineering-first decisions backed by calculations, simulation, and standards ✔ Compliance-ready documentation suitable for design reviews and certification ✔ Manufacturing-aware designs that work beyond CAD and simulation ✔ Clear, direct communication with no ambiguity or surprises ✔ Risk-focused approach that reduces redesign, delays, and cost overruns ----------------------------------------------- 📩 Next Steps If you’re seeking a reliable engineering partner to support design optimization, validation, or production readiness, feel free to get in touch to discuss your project scope and technical requirements. I will assess your objectives and outline a clear, structured approach aligned with your standards, timelines, and manufacturing constraints. ----------------------------------------------
