Sandeep is a software engineer and has worked in the United States at companies including Google, Microsoft, Citrix, Vmware and Cirtas (startup). He holds a Masters Degree in Computer Science from Johns Hopkins University. Sandeep works on technologies like data storage and compression, operating and distributed systems, mobile applications and dabbles in logo, web, graphic and UX design.

He's developed the NaadSadhana iOS app to help Hindustani Classical singers achieve perfect notes.


Sandeep is also a Hindustani classical vocalist, composer and educator. He performs and teaches all over the world. He has been learning music from the age of four and is currently being mentored by Padma Vibhushan Sangeet Martand Pandit Jasraj.

His extensive research in combining systematic forms of practice, vocal anatomy, combinatorial aesthetics, neuroscience and resilient software has given rise to a new optimized form of riyaaz called ‘Naadyoga’ which compresses 10+ hours of musical learning practice into one hour.


Sandeep has always been passionate about continuous improvement, systematic practice, efficient systems, accelerated learning and optimal minimality. He founded Endless Evolution with the aim to leverage the universe of knowledge, to evolve endlessly and share these recipes to help transform lives. 

Endless Evolution offers optimized, engaging, extensive and effective corporate training for habits like Poised, Creative, Wise, Charismatic, Loved, Lucky, Effective, Teamwork, Letting it Go, etc. 


As a musician, Sandeep derives inspiration from events in his own life and has created 75+ compositions in a variety of Ragas, Taals and Forms under the pen name 'Naadrang'.

His compositions are novel, entertaining, easy to identify with, yet don't compromise traditional values. They are expressive and span an enormous gamut of human emotion:


Version 1 - The Precision Tuner Engineered for the Human Voice
In the Gurukul system, students of music would be taught for long hours by the Guru every day. This allowed learning precise positions of notes through continuous feedback. These days, students learn a few hours a week and then practice many hours a week on their own, without guidance, making it difficult to attain note precision; they thus get into bad singing habits that are hard to fix later. 

The first version of the NaadSadhana iOS app solved this problem by providing biofeedback to gently guide the student towards the perfect note, increase both vocal and aural resolution and build muscle memory for singing perfect notes.

Version 2 - The Smart Swarmandal
Being a software engineer as well as a Hindustani Classical Singer, Sandeep is deeply interested in Computer Science and Artificial Intelligence as well as the science and art of Music. He's been fascinated by the swarmandal, a traditional string instrument, that can create a magical ambience. The swarmandal also has the ability to spontaneously 'entrain' or synchronize one’s notes without conscious effort. Unfortunately, tuning the 35+ strings of the swarmandal for a given Raga is both difficult and time consuming.

Version 2 of NaadSadhana contains a smart virtual swarmandal which is always perfectly tuned, creative, concert-worthy and understands over 100 Ragas. At the touch of a button, it will accompany you perfectly, artistically, and intelligently as you sing or play.


Naadyoga (Yoga of Sound) is a highly optimized system of learning and practice created by Sandeep Ranade. Its 7 levels cover every vocal capability that will help you create nuanced and powerful emotion effortlessly in any genre of music. Naadyoga compresses 10+ hours of practice time in 1 hour. 

This unique online course squeezes in 20+ years of experience and will transform you from a seed of potential to a universe of possibilities in a less than a year with one hour of practice a day.
