    United Kingdom - Last active: 1 month ago - Tests: 1

    Over 7 years commercial experience working on a variety of systems and data driven projects. Primary areas of speciality include SQL and Salesforce. Some examples of previously completed Salesforce projects include: • Implemented and customised a new instance of Salesforce for over 100 active users working globally across multiple business functions. • Managed a transition from a Goldmine SQL database to Salesforce. This involved a lot of data conversion work and user acceptance testing. • Writing step-by-step documentation – either aimed at a technical audience or from an end user perspective. • Developed several integrations feeding data into Salesforce using both the Salesforce Bulk and Soap API’s. Some examples of previously completed data/SQL projects include: • Writing SQL scripts to perform various database functions such as changes to table structures and record inserts. • Packaging SQL queries/stored procedures into user friendly applications such as Excel, Access or bespoke .Net applications – allowing them to be run easily by end users. • A data improvement project involving identification of gaps in CRM data; documenting recommendations for improving the quality and standardising field values; implementing data updates and introducing field validation. • Develop a small MySQL database to hold IP ranges and country data. My approach is always honest, detail orientated and friendly. I look forward to hearing of any opportunities to work together.
