[3] Stewart began working for DC around 2000, inking the last half of Deadenders, written by Ed Brubaker and penciled by Warren Pleece.

Away from the major comics publishers, Stewart wrote, illustrated Sin Titulo (Untitled in Spanish), a black and white crime story which he self-published online from 2007 to 2012.

[8] In 2014, when Gail Simone left Batgirl, Stewart took over writing the series and was joined by co-writer Brenden Fletcher, artist Babs Tarr, and colorist Jordie Bellaire.

After the series ended in 2016, the team of Stewart, Fletcher and Tarr collaborated on Motor Crush, published by Image Comics.

[9] In early 2020, Stewart worked again with Brubaker to contribute a 12-page story titled "The Art of Picking a Lock" to DC Comics' Catwoman 80th Anniversary 100-Page Super Spectacular #1.

At the time the events happened, the accusers were much younger fans, friends or aspiring artists in their teens and early twenties, and Stewart was in his mid to late thirties.
