[1] He originally competed for Russia with Anastasia Belova, with whom he appeared as the third Russian team at the 1996 Junior Worlds but they split up at the end of the season.

In September 2000, Denkova / Staviski began dividing their time between Sofia and Odintsovo, near Moscow, Russia where they worked with coach Alexei Gorshkov and choreographer Sergei Petukhov.

[1] During the last practice session before the free dance at the 2000 World Championships, Peter Tchernyshev's blade slashed Denkova's leg above her boot, severing two tendons and a muscle and leaving her unable to walk for three months.

[1] Both Denkova and Staviski fell ill with the flu before the 2001 European Championships and she suffered more swelling but they competed at the event and finished 8th, their best result to that date.

At the end of the season, they parted ways with Gorshkov and moved to Newark, Delaware, U.S., to train with Natalia Linichuk and Gennadi Karponosov.

[10] On 18 October 2007, after being put on trial for a drunk driving case which left one person dead and his wife in coma, Staviski announced he would end his competitive career.

[23] On 30 January 2008, Staviski received a suspended sentence of two years and six months, with a five-year probation period, after pleading guilty on all counts.

[26] In early January 2009, the Burgas Appellate Court reversed the suspension of his sentence and ordered Staviski to serve two-and-a-half years in prison.

[27] In May 2009, the Supreme Court of Cassation issued a final ruling in the case, which overturned the jail sentence and reduced the fines Staviski was to pay to 100,000 leva to the Petrovs and 90,000 to Gorsova's family.
