I am a Senior Mechanical Engineer with 7 years of hands-on experience in automation machine design and manufacturing-ready drawings. I specialize in converting concepts and 3D models into accurate 2D technical drawings with tolerances, fully compliant with DFM principles and real production conditions. My expertise includes: • Automation machines and mechanical systems • Detailed 2D manufacturing drawings (GD&T, tolerances, fits) • Design for Manufacturing (DFM) • Deep understanding of CNC machining, sheet metal, welding, turning, milling, and assembly processes • Design optimization for cost, manufacturability, and assembly Unlike purely CAD operators, I design based on real machining and assembly experience, helping clients avoid production issues, reduce cost, and speed up manufacturing. Availability: • Weekdays: 4 hours (flexible) • Sunday: 12–14 hours (flexible) I am highly detail-oriented, responsive, and committed to delivering production-ready designs.

• Conduct meetings, site surveys, and create preliminary layout sketches and 3D machine models, proposing innovative design improvements tailored to client requirements. • Conceptualize and draft designs for automated machinery systems based on client specifications and ideas. • Estimate costs and optimize design expenses based on preliminary drafts, presenting cost and design proposals to clients for review. Upon project approval, proceed with detailed design and refinement. • Perform testing, troubleshoot issues, and ensure systems meet performance standards and project deadlines. • Export 2D drawings, create BOM, and proceed with ordering machining services. • Independently research relevant project materials, interpret technical documents, and select cost-effective standard components. Negotiate pricing with machining vendors and collaborate with electrical engineers, robot programmers, and vision system specialists to enhance design efficiency, minimize errors, and meet client standards. • Machines designed and improved: Loader-Unloader machines, labeling machines, conveyor systems, toy car testing machines, fan assembly machines, electronic component testers, and more. • Companies involved in design projects: SDV, SDN, SIDV, SEMT, SMT, Sungwo, Hyosung, and others. • Participated in projects with investment ranging from $10,000 to $1,000,000.

I'm a mechanical Design Engineer with hands-on experience in driveline systems, rotating machinery, and test rig development. I specialise in torsional vibration analysis, natural frequency & critical speed calculations, coupling selection (SGFlex and similar), shaft design, and FEM-based validation. I help clients design robust, resonance-safe mechanical systems for engine–dyno test rigs, power transmission lines, and rotating assemblies. My work focuses on practical, calculation-driven engineering—ensuring reliability, safety margins, and smooth operation across operating speed ranges. Core Expertise: Driveline design & torsional vibration analysis (multi-mass systems) Critical speed & resonance avoidance calculations Shaft design, strength & fatigue evaluation Flexible coupling selection & alignment strategy FEM analysis for axial & torsional behaviour Mechanical test rig design & optimization Support both detailed mechanical CAD design and advanced driveline & torsional vibration analysis. I deliver clear calculation reports, design recommendations, and ready-to-use engineering tools (Excel-based calculators & templates). My goal is to provide designs that are not only theoretically correct but also practical for real-world manufacturing and testing environments. Engineer by profession, creator at heart — I enjoy driving innovation, planting new ideas, and painting robust mechanical solutions.
