CAD, Simulation & Technical Content Specialist

Fiverr • Freelance

May 2023 - Present • 3 yrs 4 mos

My role combines mechanical CAD design, engineering simulation, technical documentation, and SEO-focused engineering content. I develop detailed 3D CAD models, mechanical parts, assemblies, and 2D manufacturing drawings using Autodesk Inventor, SolidWorks, and AutoCAD. Projects involve converting concepts, sketches, reference images, and existing files into organized engineering models and documentation for product development, prototyping, and manufacturing workflows. Perform FEA and CFD analysis using ANSYS Mechanical and ANSYS Fluent, including geometry preparation, mesh generation, boundary-condition setup, simulation execution, result interpretation, and professional reporting. I also analyze outputs such as stress, deformation, pressure, velocity, temperature, and other relevant engineering parameters based on project requirements. Alongside CAD and simulation work, create SEO-driven technical articles and engineering blogs covering CAD software, mechanical design, simulation, manufacturing, and engineering technologies. Focus on making complex technical subjects clear, accurate, and useful for professional and commercial audiences. Work with clients and stakeholders remotely to define project scope, clarify technical requirements, manage deliverables, and maintain consistent communication throughout the workflow.

Mechanical CAD & Simulation Specialist

Feb 2020 - Aug 2023 • 3 yrs 6 mos

I worked on mechanical design and engineering analysis projects involving 2D technical drawings, 3D CAD modeling, mechanical assemblies, and simulation preparation for product development and manufacturing applications. Translated sketches, reference drawings, technical specifications, and design concepts into accurate CAD models using Autodesk Inventor, AutoCAD, and SolidWorks. Created detailed part models, assemblies, engineering drawings, dimensions, annotations, and documentation suitable for design review and prototyping workflows. I also supported engineering simulation projects by preparing CAD geometry for analysis, reviewing design requirements, and assisting with structural and fluid-flow simulation workflows using ANSYS Mechanical and ANSYS Fluent. I developed an understanding of how geometry, materials, loads, constraints, meshing, and operating conditions affect simulation results. It involved working closely with technical stakeholders to clarify project requirements, identify design issues, and organize deliverables according to project specifications. Contributed to improving design accuracy and documentation quality through structured CAD practices and careful engineering review. Also assisted with technical documentation that explained design features, engineering processes, and project results in clear language. This role established a strong foundation in mechanical CAD modeling, technical drawing, engineering simulation, and technical communication. The experience directly supports current Fiverr services in Autodesk Inventor CAD design, 2D engineering drawings, 3D modeling, ANSYS FEA, CFD analysis, and engineering documentation.
