Expert in the industrial services as well as development of innovative products (under the NDA and cannot be presented on my profile). With my team I successfully developed and manufactured products in mobility, goods transportation, and consumer electronics industries. We have done more than 170 projects so far, and gain experience for each product development stage: feasibility study, concept design (compliance with functional requirements and limitations of prescribed technology), concept development (detailed design of assemblies and components in accordance with the limitations of materials and production processes), production preparation (BOM creation, material, and supplier definition), Manufacturing and testing. We are highly skilled in CAD using model parameterization, bottom-up and top-down approaches, as well as dFm, dAm approaches. The design approach that we deal with relies on the production processes for which the parts are developed, to save our clients time and money by timely thinking about the technology that will be used at the end of the product development. Regarding the documentation to produce parts, we can create it in accordance with the traditional approach or the GD&T approach. We would be glad to support you on your path.
