About me

I was always interested to know how things works behind the scene. This curiosity made me explore everything I can, from software to hardware, from school days. And land up coding for six years. Made my first C++ application Quick-deal, an E-commerce app in 12th.

I have also mentored juniors in college for around a year with my designed syllabus .

I enjoy cooking while listening songs - that sooths and give peace. Traveling makes me refresh and focused.
