Hire the Best Mechanical Engineers
in the United Kingdom

I transform concepts or prototypes into manufacturable designs ready for market. I have 30 years of delivering consumer products, car interiors and even medical devices for clients and my own company. I prioritise speed to market, development cost, or product cost according to your commercial needs. Services I offer: • Design for Manufacture (DFM) • SolidWorks and KiCAD supplier build packs • Materials and manufacturing process selection • Costed bills of materials and realistic production cost targets • Mechanical–electronics integration and packaging • Assembly strategy and tolerance resolution • Supplier identification and manufacturing planning • Preparation for CE/UKCA testing and regulated environments • Trouble shooting any technical or commercial aspect of product development I can bridge between early prototypes and production with in-house 3D printing, laser cutting, assembly including specialist processes: cleanroom; low humidity; plasma surface treatment; freeze-drying; vacuum packaging. I have verified prototype and low-volume partners for injection moulding, CNC machining, pcb manufacture. I have particular expertise in development of in-vitro-diagnostic (IVD) medical devices, from concept to production, from initial concept design through rapid design-build-test cycles leveraging my in-house prototyping facilities and testing laboratory, If you are developing a physical product and need help turning a concept or prototype into a manufacturable design, feel free to get in touch. As a fellow entrepreneur, I understand sometimes you are looking for specialist advice to supplement your in-house team, for example to trouble shoot, manage a difficult supplier, decide strategic direction, or even to evaluate alternative funding routes.For this I offer direct consultation sessions on an hourly basis.

Are you looking for a mechanical design expert who can turn your ideas into precise, manufacturable solutions? I’m a Mechanical Design Engineer with 5+ years of experience delivering high-quality CAD models, detailed FEA reports, and practical design solutions. I specialize in SolidWorks, SolidEdge, and Ansys, helping clients bring their product concepts to life — from early-stage sketches to production-ready designs. ✅ Expert in 3D modeling, assembly, and drafting ✅ Skilled in FEA simulations and performance optimization ✅ Strong focus on accuracy, manufacturability, and deadlines ✅ Clear communication and client satisfaction as top priorities Whether you need product development, mechanical analysis, or design improvement, I’m here to make sure your project is completed smoothly and effectively. Let’s collaborate to make your project a success!

My background is 20 years of mechanical design in film and television special effects, which means bespoke fabricated equipment, tight deadlines, and drawings that have to work on the shop floor because there is no second chance on a film set. That experience includes a 1,000-tonne underwater rotating structure cited as the largest special effects rig ever built for a feature film. The work I do is mechanical design across the full range: concept development, detailed 3D modelling, structural and hydraulic analysis, fabrication drawings, and site commissioning. I work directly with fabricators and machinists, and I understand what it takes to turn a drawing into something that actually gets built and works first time. My primary tools are Onshape (Certified Professional) and SolidWorks, with AutoCAD for 2D work. For analysis I use Mathcad and SkyCiv. Hydraulic and pneumatic system design is a core part of my practice. My background covers fabricated steel structures and weldments, sheet metal, modular mechanical systems, motion rigs, dynamic and rotating machinery, hydraulic and pneumatic actuation, and design for manufacture across a wide range of production methods. I carry design authority on everything I deliver. I size and check my own work, document my calculations, and produce technical packages that fabricators and clients can actually use.
