I'm a 4th year B.Tech student at Delhi Technological University (formerly DCE) recently completed my 6th semester in Mechanical Engineering. I describe myself as a passionate person enjoying my work & always try to maintain a trade off between good work & time. With honesty & hardwork as my key strength. I'm very interested in the field of design & analysis, similarity of theoretical/computational results with practical experiments always hooks me up. Wishing to expertise in the field of Structural Analysis in upcoming future.
