CV / Resumé

Skills, work history and education of .NET, C#, PHP and Go developer, Andy Heathershaw.

My primary skill set is Microsoft Windows application development in the .NET family of languages, specifically C# and VB.NET. I am also well-practiced in web development using ASP.NET with an extensive knowledge of HTML, CSS and JavaScript (using jQuery where appropriate.)

As Microsoft is not the only development platform, I have self-taught secondary/alternative skills in developing back-end system services in Go on Linux or Unix platforms, Linux/Unix installation and administration, and website development in PHP with content management systems such as WordPress, ExpressionEngine and Drupal and web application development in PHP using the Laravel and Symfony frameworks.

Previously I have developed complete trading systems on Windows and Linux, including a Windows-based travel system that provided services to 100+ retail shops, 2 call centres and 30+ homeworkers – a user-base of over 700 employees. This travel system replaced one supplied by a 3rd party, saving the company over £100k in licensing and support fees.

More recently, I have played a significant role in the on-going development of the Core by Premier Software spa and wellness management software suite, including developing an open standards-based API that allows Premier Software’s clients to integrate their spa booking system in real-time with other booking channel partners.
