Txt Av have an existing application already in production that has a number of large, complex SQL queries (MS SQL 2016).
They are looking to bring in a technical expert that can take the lead on assessing performance,
making recommendations to the TxtAv app team, and then executing the code/query changes and working with the TxtAv team to migrate them through to the prod environment.
This would include testing/validating the changes in their test environments and working with the business customer to ensure data integrity is maintained.
