Growing up, Sandeep played a multitude of sports, primarily focusing on Athletics and Badminton. While playing in his native village, he injured his hip one day. Not realising the severity of the injury, which was left untreated, led to the formation of pus internally in his hip joint and Sandeep had to undergo surgery to ensure the resulting internal infection did not spread to his entire body. The result was reduced mobility in his left hip joint. He nevertheless continued playing sport and took to para sports soon after, with the javelin becoming his weapon of choice. He was a National level player in Para Badminton as well.
His father was a Special Forces Commando under the direct command of the Prime Minister of India. In 2013, a nerve related injury while on duty caused paralysis of his body, loss of memory and inability to read or interpret. Years of rigorous therapy has resulted in significant recovery, but not complete.
Sandeep won several medals at the international stage with Gold medals at the 2016 Fazza IPC Athletics Grand Prix and the 2016 Berlin Open Para Athletics Championship. His biggest achievement, although not a medal, was his 4th place finish at the 2016 Paralympics in Rio.
More recently Sandeep represented India at the 2017 IPC World Para Athletics Championships finishing 5th in his event. His most recent medal was a Silver at the 2018 Handisport Open in Paris.
