Harini Ramachandran, known professionally as Megha, is a versatile Tamil playback singer who has made a mark in the Tamil, Telugu, Malayalam, and Kannada film industries. She is also one of the co-founders of the School of Excellence, which offers programs and models based on Neuro-Linguistic Programming (NLP).

Born in Chennai, Megha is the great-granddaughter of Papanasam Sivan, a renowned Carnatic composer. She spent most of her schooling years in Bangalore before returning to Chennai to pursue a Bachelor's degree in Commerce. While studying for her Master's degree in Human Resources, Megha ventured into the field of playback singing in 2007. She has also achieved Grade 8 from Trinity College London in Western classical music under the guidance of the renowned musician Augustine Paul from Chennai.

Megha was introduced to the film industry by music director Vijay Antony in the movie "Naan Avanillai" (2007). Since then, she has collaborated with acclaimed music directors such as Ilaiyaraaja, A.R. Rahman, Harris Jayaraj, Devi Sri Prasad, Vijay Antony, and D. Imman. Alongside her singing career, Megha developed an interest in neuro-linguistic programming techniques and had the opportunity to learn from John Grinder, the founder of NLP.

In 2011, Megha co-founded the School of Excellence to offer NLP programs focused on overcoming personal issues and depression. Initially conducting sessions for individuals, Megha and her business partner expanded their efforts to reach a wider audience, including underprivileged children in missionary schools in Mumbai, helping them boost confidence and overcome personal challenges through NLP sessions. During this period, Megha and her partner developed a new technology for personal development called Excellence Installation Technology (EIT).
