Teaching was always an area where I can pursue my passion. I used to teach my friends and junior during my school and college life. After completing my professional qualification (chartered accountancy) and before joining my job, I also joined an organization for teaching and guidance to my juniors. I had also written some articles during my internship which later got published. apart from that, I have also given some presentations on certain amendments/complex issues in various forms.
