Jefray Kurnia "Jeff" Arwadi (born 1974[n 1]) is an Indonesian musician, music producer, and graphic designer.

[1] In addition to his roles in Kekal, he was also the co-founder of progressive metal project Altera Enigma and was involved with bands such as Armageddon Holocaust and Inner Warfare.

Spending most of his upbringing in a global city, Jeff had an early exposure in the diversity of culture, religion and ethnicity, which helped to form his views of seeing the music and art in a liberal way.

He once tried to become a painter but later found out that music suits him better, as he explained on the 2007 interview with Ultimate Metal webzine: "I cannot express with other media such as painting or poetry.

"[2] In 2000, Jeff graduated from Atma Jaya Catholic University of Indonesia with a Bachelor's degree in Psychology, and according to another interview with Ultimate Metal, he taught himself graphic design through books and internet.

[6] In 2006, Jeff Arwadi moved to Canada while the rest of the members remained in Indonesia, which left the band unable to play shows and do touring.

They signed licensing deals to two new record labels in Europe and North America and released The Habit of Fire a year after, which met with international success and critical acclaim.

Jeff stated that, in addition to unspecified personal reasons, he decided to leave the band because, after being closer to nature and in a less densely populated city in Canada, he was unable to continue to make dark and angry metal music which he did in the past with Kekal.

As of March 2010, Jeff decided that he needed to step away from Altera Enigma, and his contribution to the project is now minimal, although according to Jason DeRon the band will continue to take advantage of his creativity and inventiveness.

In addition to Kekal, Altera Engima, and Armageddon Holocaust, Jeff has been involved in other bands and projects including Doctor D[1] and Excision.

Despite Jeff's formal educational background in Psychology, he currently works professionally as a graphic designer specializing in print, web and multimedia production.

On his LinkedIn profile he describes his diverse skills and experience in the creative fields which include audio engineering, music production and video post-production.

[1] In 2006 he enrolled himself in an audio engineering college in Toronto, Ontario, Canada where he met his teacher/mentor Darryl Neudorf; former member of the band 54-40 and record producer of high-profile Canadian artists such as Sarah McLachlan, The New Pornographers and Blue Rodeo.

Under production inputs from Darryl, Jeff produced and recorded many of the songs released as Kekal's album Audible Minority in the college's studio facilities while he learned industry standard DAW programs such as ProTools and Logic Pro.
