Hire the Best Manufacturing Freelancers
in South Africa

I am a methodical, analytical & hands on designer with a track record of being able to work well as part of a large or small team. I have a strong technical design ability with attention to detail. I'm passionate about exploring innovative ideas and practicing intelligent design and critical thinking by drawing inspiration from simplicity with a "form follows function" approach to design. With more than 15 years professional experience - 4 years Point of Sale, 5 years Safety Apparel, 6 years Product Design, I am ready to branch out as a freelancer. My skills will cover anything the project may require, including but not limited to; Project management, Research, Sketching, Prototyping, 3D modeling, Engineering and Designing for Manufacture.

I work as an R&D Engineer in the oil and gas industry, where I design heavy machinery and structural assemblies for inspection and repair. I bring this same industrial rigor to every client project. Whether you’re building something new or fixing an existing design, I can help with: • Turning sketches, photos, or rough ideas into clean 3D CAD • Creating fabrication-ready drawings for laser cutting, bending, and welding • Fixing messy or unusable CAD files • Improving designs to reduce cost and simplify manufacturing • Assembling and validating parts before production I specialize in: Steel frames & welded structures (RHS, structural components) Sheet metal parts & enclosures (folded, cut, production-ready) Industrial equipment, brackets, mounts & assemblies I don’t just design—I design with real-world fabrication in mind, including processes like welding, forming, and post-processing. With experience in both mechanical design and fabrication environments, I understand what works on screen vs what actually works in the workshop. If you need a design that’s clean, practical, and ready to build—send me a message and let’s discuss your project.

Mechanical Design | CAD Modeling | Product Development I help manufacturers, prototyping teams, and engineers turn ideas into production-ready designs. From concept to detailed CAD, I deliver reliable support tailored to real-world manufacturing. With over 6 years of hands-on experience, I specialize in: 3D CAD modeling using SolidWorks and Autodesk Inventor Manufacturing-ready 2D drawings (including GD&T, BOMs) Assembly, enclosure, fixture, and jig design Design for 3D printing (FDM) and STL cleanup SolidWorks and Excel tool development for process automation Design for manufacturing (DFM) and practical problem solving Clients choose me for clear communication, fast turnaround, and reliable results-without the overhead of hiring full-time. Certified SolidWorks Professional (CSWP) Based in South Africa | Serving global clients remotely Let’s connect to see how I can support your next project, whether it’s a quick prototype or long-term collaboration.

I am a Mechanical Engineer and Top Rated Plus Upwork freelancer with $275K+ earned, 85+ completed contracts, 3,000+ hours, and extensive experience solving complex engineering problems for startups, manufacturers, R&D teams, and established technology companies. My work spans CFD, FEA, thermal management, turbomachinery, HVAC, electronics cooling, aerospace, automotive systems, pressure equipment, product development, and manufacturing. I am also an inventor on USPTO-granted cooling-system technology, including US 12,452,991 and US 12,453,048. WHAT I CAN HELP YOU WITH CFD & FLUID FLOW • Heat exchangers and thermal systems • Centrifugal fans, blowers, impellers, and volutes • HVAC, ducts, plenums, and airflow distribution • Electronics and enclosure cooling • Refrigerant and thermodynamic systems • Pressure-drop and flow-network optimization • Conjugate heat transfer • Natural and forced convection • Multiphase flow and species transport • Rotating machinery using MRF or transient methods • Turbulence modelling including k-ω SST, realizable k-ε, and LES where appropriate FEA & STRUCTURAL ANALYSIS • Static structural analysis • Stress and deformation • Fatigue and durability • Nonlinear materials and contact • Drop, impact, and shock analysis • Modal and vibration analysis • Buckling • Pressure vessels and pressure-containing components • Composite structures • Topology and weight optimization • Bolted, welded, and bonded assemblies CAD & PRODUCT DEVELOPMENT • SOLIDWORKS parametric modelling • Complex assemblies • Surface modelling • Sheet metal and weldments • Injection-moulded components • Machined and cast parts • Design for Manufacturing and Assembly • Tolerance analysis • Production drawings • Prototype development • Manufacturing-ready CAD packages THERMAL & NVH • Electronics cooling • Heat sinks and cold plates • Liquid cooling • Heat exchangers • Thermal resistance optimization • Fan and airflow acoustics • Noise and vibration investigation • NVH analysis WHY CLIENTS HIRE ME I do not provide black-box simulations with screenshots and a “trust me” conclusion. My simulation work is built so that your engineers, investors, manufacturers, or certification teams can understand and defend the results. Depending on the project, deliverables can include: • Mesh-independence and convergence evidence • Y+ verification • Residual histories • Boundary-condition justification • Analytical or experimental validation • Pressure, velocity, temperature, stress, and deformation plots • Flow-uniformity analysis • Parametric design comparisons • Design recommendations • Manufacturing implications • Executive engineering summaries • Native simulation and CAD files For optimization-heavy projects, I also use Python-driven automation with OpenFOAM and other solvers to evaluate design spaces far beyond what is practical using manual simulation workflows. SELECTED ENGINEERING WORK 224,000-POINT CFD OPTIMIZATION — HEAT EXCHANGER Built an automated CFD optimization workflow for a centrifugal heat-exchanger architecture. A 224,000-point design-space sweep identified geometry changes capable of more than doubling predicted system COP.
