Senior Mechanical Engineer with 14 years of experience and 35 verified 5-star reviews on Freelancer. I turn concepts, sketches, and existing CAD into manufacturable products and engineering solutions validated before fabrication. Core services: • Mechanical and product design in SolidWorks • 3D CAD assemblies, mechanisms, and production drawings • Structural FEA and design validation in ANSYS/SolidWorks Simulation • CFD for airflow, ventilation, cooling, and pressure-loss studies • DFM for machining, sheet metal, welded frames, and molded parts • BOMs, exploded views, STEP files, tolerances, and assembly documentation • HVAC, plumbing, MEP, and BIM coordination in AutoCAD/Revit What clients receive: • A clearly defined scope, assumptions, and milestones • Practical engineering decisions—not CAD geometry alone • Organized, manufacturing-ready files and concise reports • Proactive communication and early warning of technical risks My recent work includes industrial cooling systems, CFD ventilation studies, adjustable fabricated structures, mechanisms, enclosures, and production-ready product development. If you need a reliable engineer who can connect design, analysis, and manufacturing, send me your brief, sketches, dimensions, and required deliverables. I will review the scope and suggest the most efficient path forward.

CFD Flow Modelling Collaboration NDA

If you're looking for bottom-dollar basics, this is not the freelancer for you. Professional from the outset, Gokay took time to understand the brief, suggest a sensible payment structure and advise me of his other commitments. Throughout the project I was well informed and he made a number of sensible design change suggestions. His knowledge of CFD is excellent and he took great care to produce a thoroughly professional report that we will use for the next phase of development.

Structural CAD Designer Needed for Slim Wall-Mounted Media & Electric Insert Frame System

Excellent experience working with Gokay. Very professional, responsive, and easy to communicate with throughout the entire process. They were patient with revisions, open to feedback, and consistently worked to improve the design rather than just delivering the minimum. The final files were detailed, organized, and high quality, and the overall presentation looked very professional.

Another project completed with Gokay, and once again he delivered outstanding work. A great success once more primarily due to his unwavering commitment. I highly recommend him and will continue working with him on future projects.
