Vadym's wife used to work but her income was so low they decided there was little point - Vadym now supports the family.
Vadym Mamedov fell into selling American auto-parts by accident.
He helped a man find a part for an American car on one occasion. Then other people asked him to get parts for their vehicles. He now has a business in a market entirely full of tiny stalls selling car parts.
There are many such markets all over Ukraine and flea markets are a common sight in the capital, Kiev.
The biggest issues for him are taxes - "If a part costs $2 in America, here they would cost 10 times more, you need to pay a lot of money to different people" - and the weather.
In the summer it can get up to 40 degrees Celsius and in the winter the temperature plummets to well below zero. Vadym stands for nine hours or more with no heating or air conditioning.
But for his efforts he earns about $1000 a month to support himself and his wife.
