He then started making motivational videos on Instagram. His videos are also available on his self-titled YouTube channel. In an interview, while talking about making motivational videos, he said,

My first ever video was about ‘demotivating people’. But I don’t call myself a motivational speaker; I talk about what I have experienced in my 29-year-old life – very simple and relatable things, as you can see. Things we fail to notice. When the number of followers increased, people started to direct message me. I get a minimum of 2,000 messages every day, from eighth graders to middle aged men. I found that they feel comfortable to disclose their problems to me. I never knew I could make such a difference. I reply to every text message, hoping that my little effort may help them. On the other hand, I am a very normal person. I can be upset and moody at times. But when it’s about bringing smile on someone’s face, I try my best to be selfless.”

He has featured in a few Malayalam cover songs like “Mizhiyariyathe” (2018) by K S Harisankar, “Pavizha Mazhaye” (2019) by K S Harisankar, and “Jiya Jale” (2019) by K S Harisankar.
