In the early 1970s, he was an William Vance's assistant on the backgrounds of 'Bruno Brazil' and 'Bob Morane'. Afterwards, he began working for Albert Weinberg. He then found a job in the construction field, where he could use his architecture background. He met Delaney in 1984.

Then, they came up with the 'Alexe' series. The series first appeared in the magazines of the Vers l'Avenir group, and then in albums. When the publisher Alpen cancelled the series, Jaradin assisted Magda on the backgrounds the 'Charly' series. In 1994, the 'Alexe' series was revived at the publishing house Claude Lefrancq and Jaradin teamed up with scenarist Michel Oleffe to begin new stories.
