Early 1900 or late 1800 i think but what was he in the swedish army and what medals do he have on his left chest

The uniform is a m/1895 uniform. That was used by the mounted life guards, the life guards-, the scania- (Skånes) and the north- (Norrlands) dragoon regiments. It was also used by the service (Träng) regiments but they had a dark blue uniform, this one looks more like the cavallry units middle blue uniform. 

 

The photo shows a collar with two stylized button holes, this style was used by the mounted life guards on a middle blue collar (the life guards dragoons had an all white collar, the scania dragoons had a yellow collar and the north dragoons had an orange collar). The buttons also seems to be silver indicating mounted life guards as well.

 

The button holes on the collar and the sleeves, the epaulettes and the piping on the coat and trousers seems to be white indiacting that this man wasn't an officer as these details then would have been silver. The single scholar stripe on the left overarm indicates finished corporals school.

 

As a summary: my conclusion is that this is a corporal at the mounted life guards (K1) based in Stockholm. Ha has a m/1893 enlisted mens sabre. Unfortunately I cannot identify the medal and the badge.

 

Best regards
