Am a results-driven Mechanical Design Engineer with 8+ years of experience delivering innovative, cost-effective mechanical systems, components, and prototypes. Proficient in SolidWorks (3D modeling, sheet metal, FEA simulation), ANSYS for finite element analysis, Autodesk Inventor, AutoCAD, LANTEK and LIBELLULA Sheet metal cutting optimization. I specialize in designing manufacturable parts and assemblies, performing tolerance analysis, GD&T application, engineering calculations, simulations, and ensuring compliance with safety, quality, and industry standards (e.g., ASHRAE, BS). In MEP building services, I excel at creating integrated systems for HVAC, plumbing, and electrical designs. Using Revit MEP, AutoCAD MEP, and HAP for load calculations, I've prepared shop drawings, coordination drawings, and as-built documentation for complex projects, ensuring 100% installation accuracy and seamless revisions. My work supports architects, consultants, and site teams in resolving onsite issues, maintaining version control, and adhering to project specs—reducing rework and enhancing efficiency in construction environments. Key achievements include: Reducing component weight by 40%+ and improving strength via ANSYS FEA, cutting manufacturing and lifecycle energy use. Shortening design-to-prototype cycles by 70% through optimized modeling and simulations. Boosting team deadline adherence by 60% with efficient CAD workflows and project management (MS Project, ClickUp, Agile/Lean). Overseeing prototype development, physical testing, validation, BOM/BOQ preparation, technical drawings, and cross-functional collaboration to resolve manufacturing/field issues. From steel structures and elevators to MEP systems and fuel-efficient vehicle designs (Shell Eco-Marathon project: 200% weight reduction), I bring hands-on fabrication knowledge, laser cutting optimization, and a focus on precision and efficiency. Passionate about mechanical engineering in manufacturing, energy, automotive, MEP building services, and product development. Ready to help turn your concepts into high-quality, compliant products on time and within budget. Let's discuss your project—message me today!
