John has been working in IT since 1992 and started using SQL Server as a client/server developer in 1999. He has been a SQL Server DBA since June 2000. In that time John has developed some great working relationships with clients and colleagues alike.
John used to be an application developer using FoxPro/Visual FoxPro and loved making it go faster, so when he became a SQL Server DBA; he was always writing scripts to get the best out of SQL Server. He has experience as a production DBA, a T-SQL Developer, a Reporting specialist (SSRS & Power BI) and creating Data Warehouses.
He delivers several courses about DBA,T-SQL, BI and Power BI. He has set-up data warehouses for banks in the UK and has also performance tuned data warehouses, as well as lots of transactional databases, typically by using Sequallity’s SQL Server Health Check.

Having worked in London for 5 years and all around the country for the last 14 years or so, getting to your site shouldn’t be a problem but if you are miles from Northampton or London then please let us know. We typically don’t charge expenses but if your business is on the Shetland Islands, we might provide a quote to include travel.
We also provide remote DBA support if requested, typically this is to help our clients who are in a bit of a pickle and need support now.
