Introduction

I'm a mechanical engineer graduated in 2021, having interest towards aerodynamics and product design. I have won an award at DRDO, Chandipur for developing my own FLIGHT CONTROLLER for Multi-rotors and fixed wings. I've been in the Society of automotive engineers (SAE) as the technical head in the steering and suspension department and have participated in events like BAJA SAE, MEGA ATV CHAMPIONSHIP etc. Evolving of new designs of products/structures and it's development keep motivating me always. I'm fond of spending the valuable hours in learning and developing the skills, that are very much essential to carry as a strong and qualified engineer. And I'm looking for opportunities to be a valuable asset for catering the growth of the company I'd work for. And in the meanwhile, learning more new things will be always on the way. If I can be of your help or can serve for your purpose, kindly reach me at shubhajit98@gmail.com or +91-8093245637.
