About OSX

OSX has been developing web based solutions for over 10 years, including everything from simple websites with a couple of pages, to large database driven web applications with thousands of pages and user interactivity, as well as solutions you may not immediately associate with web technologies such as company intranets / extranets and mobile targeted applications.

Based in Swindon, Wiltshire, OSX is run by Andy and Kris, who have been working together for a decade, originally as two independent companies with near constant collaboration, which then merged in 2007 to form OSX in its current state today.

The Team


Andy Holt Managing Director

The vast majority of your interaction with OSX will be via Andy, be it going over your initial ideas, compiling your project's specification, developing the design work, or answering your questions when you're up and running with your new website. Andy has been working with the web since the 90's and directly with clients for just as long!


Kris Willis Technical Director

With over 12 years of experience in the technical design and development of web based applications, Kris has the ability to turn your requirements into fully functional online solutions, he also ensures we're always on top of the ever changing technologies and techniques relevant to the web development industry.

Andy P

Andy Preston Developer

Andy has been involved in all kinds of software development for more years than he cares to remember. Andy likes to find technical solutions to real-world problems without loosing sight of the big picture.

Our Associates

Although all of the technical development is carried out in-house at OSX, there are occasions when we need to call in expertise from our local network of professionals; likewise, we've also provided development services when needed, too. Here are some of the people we've worked with regularly.
