June 2010 to May 2012
A market-leading, popular corporate gambling and online gaming enterprise
Senior PHP Developer - Accounts and Third Party Services Integration Team
Part of a team providing a high-quality level of service subject to aggressive time-scales for a large-scale, multilingual, business-critical system responsible for handling customer registrations and payments. The system was served by a very large Oracle database with packages, functions, tables, foreign-constraints and triggers. Developed and updated internal web-services using SOAP/Rest and integration with external third-party web-services. Due to company restructuring and a management-buyout, the in-house IT departments were replaced by outsourced pre-built solutions, resulting in redundancies. PHP, Zend, Oracle, Smarty Templates, Red Hat Linux, CAB auditing, Mercurial.
Achievements:
• Assisted development of the customer registration re-skin to modernise and improve the open-account user-experience resulting in a turnover increase of over £300k within the first month
• Worked on multiple projects to improve the system during my downsizing notice period that led to substantial returns on investment beyond my employment at Gala Coral
• Improved architecture by incorporating Zend Framework components into the system
• Responsible for organising and delivering the team's Requests For Change (RFC) and Change Authorisation Board (CAB) submissions during a three month period when the CAB practices were tightened, which resulted in a new benchmark of CAB audit reliability recognised by other divisions and high-level executive management.
• Adopted and updated a neglected internal wiki and drove documentation improvements that turned around poor knowledge-transfer and technical transparency of a very large scale business-critical system, setting a standard of reliability and readability that the entire team followed and improved upon
