From 2007 to 2008 he served in the armed forces on the territory of Aghjabadi District of the Republic, then he was transferred to the Central Sports Club of the Ministry of Defense as a promising sportsman.
Aghayev was never faced with a question to go in for sports or not, since his father, being a professional soccer player, cultivated love for sports to him and also to two older brothers. The oldest brother Ruslan began to train in judo, the second brother Rustam involved in boxing and has good results.
Aghayev, like many other boys from childhood had to find their place in life, and he began following in the footsteps of his father, from 7 years became involved in football and at the same time began karate trainings in the sports class of his first coach Rafael Mammadov, who cultivated great love of karate to him and taught the first skills. This went on for several years. Participating at the first national competitions, he was noticed and invited to train in one of the famous sports clubs of the Republic «Budokan» under the leadership of Fizuli Musayev.
Already at the first championship of the Republic, Rafael won an overwhelming victory over all his rivals, and was noted by the President of the National Karate Federation Yashar Bashirov, who saw in him great potential and unusual tactics of fight. Aghayev was very diligent and had a will to win, but he lacked international experience. At the international level competitions, he first took part in the composition of the National Team in 1997, at an open World Cup in Miskolc (Hungary). Unfortunately, the first performances were not successful, but already next year he won the Open Championship of England and then hardly ever lost.
At his first World Championship among Cadets and Juniors, which was held in 2001 in Athens (Greece), in the team event he went to 3rd place, and the following year became the European Champion. Thus, up to this day he holds the leadership in his weight class. Without exaggeration we can say that Aghayev is one of the strongest karate sportsmen in the world. Despite his young age, he managed to achieve all of the highest sporting victories in karate; he is multiple European Champion, repeated World Champion. He holds the record, when at one World Championship; he was able to win two gold medals. This happened in 2008 at the 18th World Championship in Tokyo, when he won in the weight category of 70 kg and the other one in the open category (open). The President of the World Karate Federation, Antonio Espinosa called him – «Diamond of the Karate World».
Important role in the sports career of Aghayev played a senior team coach Hidayat Shabanov, who during more than 8 years trained him and shared with him all the joy of victory. For outstanding sports achievements at the international arena Aghayev repeatedly has received an awards from the leadership of the National Olympic Committee, the Ministry of Youth and Sport of Azerbaijan Republic, several consecutive years he entered the ten best sportsmen of the country. From the official sponsor of the Federation, the International Bank of Azerbaijan he received the keys from a new apartment in one of the elite areas of the city, as well as automobile Audi Q7.

In June 2015, he competed in the inaugural European Games, for the host country Azerbaijan in karate, more specifically, Kumite for 75 kilograms. He earned a gold medal.
