His adult life spent as a full-time carer for his disabled mother, John began writing as a means to escape into different worlds. He penned the short film, Long Lost Father in 2014, which premiered at FilmFest Gent as part of the anthology film, Follow: Tall Tales From a Small City (2014).

Having struggled to balance his caring commitments with his craft, John took a break from writing but has again put fingers to keys, writing four contest-placing teleplays in 2021. His horror pilot script, Demonica, was named as a Finalist in both the Los Angeles Crime & Horror Film Festival Screenplay Competition and the Santa Barbara International Screenplay Awards, while his urban fantasy pilot, Guardian of Ash, also achieved a Finalist placement in the latter competition.

John prefers to write in the horror, sci-fi, and fantasy genres, and having grown up watching a slew of 80s horror movies, has a strong preference for writing female protagonists.

John is also a member of the Writers' Guild of Great Britain.

Off-screen, John has been a frequent contributor to movie publications, including the books Hidden Horror, When Animals Attack and Dr AC's Horror 101, along with the website CultReviews.com. 

He holds a BA in Humanities, including a Distinction-level pass in Advanced Creative Writing from the Open University.
