About Me I am Mahalingam Sanjeev Kumar, a freelance tooling and process engineer with over 25 years of experience in engineering design, manufacturing coordination, and project delivery. My work is rooted in practical design, vendor collaboration, and process clarity—helping clients move from concept to completion with confidence and precision. I specialize in SolidWorks-based design workflows, RFQ preparation, process evaluation, and manufacturing coordination. My role is not just to design, but to ensure that every part, tool, or assembly is manufacturable, cost-effective, and delivered with purpose. I work closely with suppliers and vendors to streamline quotations, plan processes, and manage execution—all while maintaining clear, boundary-aware communication. I operate independently, but always in sync with the needs of the client and the realities of the shopfloor. Whether I’m preparing a quotation, refining a design for manufacturability, or coordinating with a casting vendor, I bring a quiet intensity and a commitment to ethical, efficient work. My current focus includes: • CAD design and documentation • RFQ preparation and vendor coordination • Process evaluation and planning • Manufacturing support and delivery • Quotation review and cost optimization I believe in clarity, consistency, and continuous learning. My work is not just technical—it’s relational. I care about how designs are received, how they perform, and how they reflect the values of the people behind them. Based in Coimbatore, Tamil Nadu, I actively engage with clients and suppliers across Bangalore, Pune, and Chennai. I’ve been researching casting vendors, preparing modular outreach drafts, and refining quotation comparisons—all with a focus on privacy, professionalism, and long-term collaboration. If you’re looking for someone who can quietly elevate your design process, support your manufacturing goals, and communicate with clarity and respect—I’d be glad to connect. .
