During my undergraduate i used to participate as TA (Teaching Assistant) in several electronics and computers subject. I'm passionate about learning Computer Science as my bachelors are in Electronics but i learnt most of the Computer Science subjects on my own which Machine Learning also. At Present, i'm a working professional pursuing my career as a Machine Learning Engineer and i want to help others learn during my free hours, that's all the motivation behind giving tuition. To be frank i have no prior experience of tutoring but i have solved problems on opensource platforms like StackOverflow and github. ~Thanks
