Experience managing and maintaining SQL Server, integration with numerous third parties such as Salesforce, AppDynamics, New Relic, Dynamics CRM and many payment gateways.

The first Sitecore website I developed was Skiweekends which was architected and developed by me. It won the Sitecore Experience Award the main award during the Sitecore Experience awards ceremony and the Sitecore Best Travel & Tourism award. I also was lucky enough to perform the first Sitecore 8 upgrade within the United Kingdom for Liberon.
