Pulkkinen was born in Helsinki. At the age of 6 he started studying piano and composed his first song at the age of 12. He was interested in the computer music demoscene and started making music with tracker software under the name "ArtZ". He won many music competitions and made his first big public album to accompany a freeware game named "Starfight VI: Gatekeepers" in 1999. Ari has never studied music composition academically.

In 2003 he was hired as in-house audio director to game development company Frozenbyte Inc. Where he made the original soundtracks and sound design for video games Shadowgrounds, Shadowgrounds: Survivor and Trine. In his spare time Ari earned diplomas in Professional Audio Design and Producing and Further Education for Producers and Leads of the Finnish Game Industry with Adulta, and Music Technology with Sibelius Academy. After quitting Frozenbyte in 2008 (though he continues to have a professional relationship with them), Ari started his own sound production company AriTunes. Since then he has made original soundtrack and sound design for over twenty projects, including video games such as Angry Birds, Dead Nation, Trine 2, Outland and Super Stardust HD. Ari releases his music through AriTunes.

On 2 September 2011 in Video Game Heroes Concert, "Angry Birds Theme" was played by London Philharmonic Orchestra. This is the first time Ari's music was played by a full live orchestra.

On 4 October 2011, Ari won the Best Finnish Game Developer in 2011 Award due to his contribution in the Finnish game industry.
