Karthik Doddaballapura

Mechanical Engineer

Passionate Mechanical engineer with keen interest in product engineering and management. Mechanical engineer from Visvesvaraya Technological University & Masters in Automobile Engineering fromCoventryUniversity.

With over 15 years of product design and development experience comprising of Electronic Power Packages, Molded products and heavy engineering equipment’s design. I have managed product design from ideatoreliability.

My product engineering and management experience has given expertiseon mechanical,electricaland optical engineering . I have gained key expertise in Structural, Thermal, Thermo-Mechanical & Vibration simulations. I have also worked on scripting to help automate and improvise workflow. Tool experience include Solidworks professional, Fusion360,Inventor,ANSYS&Python.

My keen interest to help design better products has led to use efficient design methodology and process like DRBFM-Level4expert(DesignReview

Based on Failure Mode) , FMEA, PPAP, 8D,DFMandDFR.

I am currently enrolled to PEO and in process of obtaining P.Eng. I have completed my CAEM and now working onobtainingmyPMPcertification.
