Hari's first big success was winning the Swiss Junior Championships in giant slalom in January 1998. A month later he won the bronze medal in Super-G at the Junior World Championships .
From the following winter, Hari started regularly in the European Cup . His breakthrough came in the 1999/2000 season , when he celebrated his first win on January 27, 2000 in the downhill from Les Orres and finished fourth in the downhill classification at the end of the season. In the next few years he achieved numerous top 10 places in downhill runs and Super-Gs, and occasionally he even made it onto the podium. In the seasons 2001/02 and 2002/03 he reached fourth and fifth place in the Super-G classification. At national level, he celebrated his greatest success in 2004 when he became Swiss Super-G Champion . However, Hari had to wait five years for his second victory in the European Cup. He only succeeded in this on January 9, 2005, when he left Bad Kleinkirchheim . The next day, he finished first in the second downhill run and thus secured victory in the downhill classification in the 2004/05 season .
In the World Cup , Hari came into the points for the first time on February 13, 2000 as 24th in the Super-G in St. Anton . For more than four years this was his best result, as he rarely got a place in the top 30. At the beginning of December 2004 he achieved a top position for the first time with twelfth place in the Super-G of Beaver Creek and in the further course of the 2004/05 season he was four times among the fastest 20. The Swiss achieved his best World Cup result on January 20, 2006 with a place ten in the Super-G of Kitzbühel . However, he still lacked consistency, because in the other races of the season he was only once again among the top 20. After an injury at the beginning of the 2006/07 season, he had to pause for over two months. Only at the end of the season did he take part in World Cup races again, but remained without points. In the 2007/08 season he was only among the top 30 in two World Cup races. In 2008 Hari announced his retirement from ski racing.
