Somehow Teimur Aliev manages to smile. A lot.
The 23-year-old musician is in Kharkiv, a city in northeastern Ukraine that has suffered some of the heaviest bombardment from Russian forces and where dozens of civilians have been killed.
Rather than fleeing, he has decided to remain in his home town and try to help those who are either trapped or, like him, staying put.
As soon as the war began on Feb. 24, Aliev and his older brother Ramil collected all the money they had and bought food and other essentials, which they distributed to people who could not get to shops themselves.
From a small beginning, his venture has expanded with the help of social media to involve dozens of volunteers who get as many supplies as they can from wholesale warehouses and shops, bring them to a collection point and distribute them by car and on foot.
The aspiring blogger has recorded his experiences on camera and shared footage on his Instagram account.
As he drives through Kharkiv, his videos show badly bombed buildings lining wide streets, burned out cars riddled with shrapnel holes and debris strewn across the ground.
Aliev remains resolutely upbeat.
"I am a young guy, a rapper, a musician who was just lying at his home on the outskirts of the city of Kharkiv," he told Reuters, describing the start of the shelling. "I ... started waking up to a terrible rumbling noise."
"There was a very scary rumble. There were explosions everywhere, explosions, explosions, explosions."
In an interview recorded over Zoom, he added: "We will stitch up the wounds and the pain of our country and our city. We are ready to build it and we are ready to renew it when the war is over. We're not going anywhere."
Moscow has denied targeting civilians in the war, which it calls a special operation to demilitarise and "de-Nazify" Ukraine.
Aliev, who is half-Azeri, half-Ukrainian, said people from overseas had initially donated money, but that the war had made withdrawing cash from banks much harder.
He is asking people to send food instead - still technically possible because Kharkiv is not yet cut off by Russian forces.
Footage and photographs he shared feature him and his helpers delivering groceries to families sheltering in basements and elderly people in a dormitory.
They also show friends handing flowers to women on Women's Day on March 8 - a major public holiday in former Soviet countries like Ukraine but one that was largely forgotten in the war zone. As a violinist plays, some women grin, others cry.
Aliev said that once he got over his initial fear when the shelling began, he has managed to remain positive - for the sake of himself and others.
"Well, what is the point of being afraid?" he asked. "A smile is the most important thing. A smile gives kindness to all other people."
