I help companies turn product ideas into functional, manufacturable designs — from concept development and 3D CAD modeling to prototype-ready solutions. With 20 years of experience in product development and manufacturing environments in China, I bring practical engineering knowledge from injection molding, tooling, and production processes into every project. My strength is not only creating CAD models, but understanding how products will actually be manufactured, assembled, and improved before moving into production. My professional background includes: • 7+ years in injection mold design and tooling development • 5+ years in plastic product design and mechanical engineering • 6 years managing engineering projects and localization programs • Experience working with international customers, suppliers, and manufacturing teams My services include: ◆ Plastic Product Development - Concept development and mechanical design - 3D CAD modeling (Siemens NX) - Product structure optimization - Prototype-ready design - Design improvement based on function, assembly, and manufacturability ◆ Design for Manufacturing (DFM) - Plastic part design review - Wall thickness, rib, boss, snap-fit optimization - Draft angle and molding considerations - Material and process recommendations - Risk identification before tooling ◆ Manufacturing Cost & Production Optimization - Manufacturing cost driver analysis - Design optimization for cost reduction - Tooling cost evaluation - Mold configuration recommendations - Material selection for cost and performance - Production feasibility assessment - Supplier quotation review - Manufacturing process optimization ◆ Injection Molding & Manufacturing Support - Mold feasibility review - Tooling risk assessment - Technical communication with manufacturers - Prototype and engineering change support I have worked on projects including industrial components, plastic products, and consumer products where practical engineering decisions are critical. If you need an engineering partner who can improve manufacturability, reduce production risk, and optimize manufacturing cost before tooling, I'd be happy to discuss your project.

I build mechanical products beyond the CAD screen. I work at the intersection of mechanical design, product development, engineering analysis and physical prototyping — turning engineering problems into hardware that can be manufactured, tested and refined. My experience spans industrial systems, railway safety, medical & assistive technology, machinery and R&D applications, giving me exposure to the complete product-development cycle: Problem → Concept → Design → Analysis → Prototype → Test → Refine My core engineering capabilities include: 1. Mechanical & Product Design: 3D CAD modelling, mechanism design, assemblies, engineering drawings, and design optimization. 2. Engineering Analysis: FEA, structural analysis, design validation, and engineering-based material and component selection. 3. Manufacturing & Prototyping: DFM/DFA, machining, fabrication, sheet-metal development, additive manufacturing, reverse engineering, and prototype development. Tools: SolidWorks (CSWA & CSWP) • Fusion 360 • ANSYS • AutoCAD • Autodesk Inventor A significant part of my experience comes from working on real engineering systems rather than isolated CAD exercises — where manufacturability, cost, material selection, tolerances, fabrication constraints and functional performance all have to work together. I have contributed to projects involving Southern Railway – Thiruvananthapuram Division and SCTIMST, including railway safety systems, assistive mobility technology, medical equipment, and industrial engineering solutions. Alongside my engineering career, I have also been involved in building Hesper Tech Pvt Ltd, an engineering product-development venture, where I have worked across mechanical design, R&D, prototyping, technical documentation, and multidisciplinary engineering projects. I am particularly interested in engineering challenges where the objective is not simply to create a good CAD model, but to develop a solution that works in the real world.
