Nostex is a small tech company based in Essex UK, founded by John Sexton in 2014.

About Me

I have a mixed background of music and web tech. Previously a mix DJ, started out with vinyl before moving to CDs and later experimented with DVS (digital vinyl systems). I worked for a London NHS for twelve years as a web developer before starting Nostex.

My web skills mostly lay with open-source tech like PHP, MYSQL, JavaScript, HTML & CSS. I’ve also worked with various frameworks like jQuery, Bootstrap & CodeIgniter. I’ve worked with XML, JSON and various APIs. I’m not a graphic designer on account of having very limited sight but have worked with SVG.

I have specialist experience with web accessibility and have a blog at www.abc4accessibility.com. I wrote the kindle book, Understanding Web Accessibility and People. I’m also an advercate of Braille and you can read a little on my site at www.braillemedia.co.uk.

More recently I have started working in sound design using virtual synths in Reason, the music software by Propellerheads. I also setup the Reason community website www.reasonremoter.uk, that offers information and downloads for the Reason MIDI control system called “Remote”.
