Available to hire
Hi, I’m John Tyrrell, a mechanical engineer specializing in end-to-end product development for consumer goods, medical devices, and industrial components. I bring hands-on prototyping, 3D CAD, and manufacturing know-how to deliver robust designs from concept through tooling and production. I thrive in cross-functional teams and love turning complex challenges into practical, repeatable solutions.
In my work, I lead design for manufacturing, coordinate with suppliers, and communicate clearly with clients to ensure on-time, on-budget delivery. I’m passionate about reliability, manufacturability, and applying rigorous analysis (FMEA, root cause analysis, FEA) to produce safe, scalable products.
