Karthik Doddaballapura Mechanical Engineer
Karthik Doddaballapura
Passionate Mechanical engineer 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 idea to reliability .
My product engineering and management experience has given expertise on mechanical, electrical and 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, Autodesk Inventor and AutoCAD, ANSYS & Python .
My keen interest to help design better products has led to use efficient design methodology and process like DRBFM - Level 4 expert (Design Review Based on Failure Mode) , FMEA, PPAP, 8D, DFM and DFR.
I am currently enrolled to PEO and in process of obtaining P.Eng. I have completed Six Sigma – Green belt and now working on obtaining my PMP certification.
