I am a final-year B.S. Mechanical Engineering student at the Pakistan Institute of Engineering and Applied Sciences (PIEAS), with a strong interest in CAD design, 3D modeling, robotics, thermal-fluid systems, and practical product development. I enjoy turning rough ideas, sketches, and engineering concepts into clean, accurate, and manufacturable designs. My main skills include SolidWorks, AutoCAD, Ansys, MATLAB/Simulink, 3D CAD modeling, engineering calculations, structural analysis, CFD, and technical documentation. I focus on creating designs that are not only visually clear but also practical for real-world use, prototyping, and manufacturing. One of my key projects is the design and analysis of a 4-DOF robotic arm, where I worked on CAD modeling, kinematic modeling, stress analysis, and fabrication planning. I also have experience with Unmanned Aerial Systems (UAS), renewable energy configurations, heat exchanger analysis, and mechanical system design. Along with my academic background, I have hands-on internship experience at the PAEC, where I gained exposure to welding, inspection methods, and non-destructive testing. This helped me understand how engineering designs are connected to actual manufacturing processes and material limitations. I am detail-oriented, reliable, and always focused on delivering clear, functional, and well-organized engineering work. Whether you need a 3D CAD model, 2D drawing, design improvement, basic analysis, or technical documentation, I would be glad to help bring your project idea to life.

Service Overview Stop struggling with uneditable mesh files and "unprintable" geometry. I provide professional Mechanical Engineering services to transform your concepts, 3D scans, or broken STL files into high-precision, production-ready CAD models. Whether you need a custom enclosure for a PCB, a replacement mechanical gear, or a complex assembly, I engineer every file with Design for Manufacturing (DFM) principles to ensure a perfect print the first time. What I Specialize In: 1. Advanced Reverse Engineering (Mesh to CAD) STL / OBJ / PLY to STEP: I don't just "auto-surface." I manually rebuild your mesh into a clean, parametric SolidWorks model. Modification & Repair: Need to change a hole diameter on an STL? I can modify existing mesh files and export them as editable CAD data. Deviation Analysis: Ensuring the digital model perfectly matches the physical dimensions of your original part. 2. Engineering for 3D Printing (DFM) Tolerance Management: Custom clearances (0.1mm - 0.3mm) based on your printer type (FDM/SLA/SLS) so parts snap or bolt together perfectly. Structural Optimization: Adding ribs, fillets, and correct wall thicknesses to prevent warping and ensure mechanical strength. Complex Enclosures: Designing waterproof (IP68) or ventilated casings with integrated mounting points for electronics and batteries. 3. Mechanical Simulation & Validation FEA Stress Analysis: Testing your design under load in SolidWorks Simulation before you waste filament or resin. Mechanism Design: Creating multi-part assemblies with functional joints, gears, and linkages. Deliverables You Will Receive: Production Files: High-resolution STL and 3MF optimized for slicing. Engineering Files: STEP, IGES, or X_T for CNC machining or future editing. Source Data: Original SolidWorks (.SLDPRT / .SLDASM) files upon request. Technical Drawings: 2D PDF/DWG drawings with dimensions and tolerances.
