Hello! I am a Computer Engineer, with a MCSA SQL Server 2014 certificate, with more than 10 years of experience using SQL, queries, reports and dashboards design and construction, data warehousing, and overall Business Intelligence related projects and tasks. I am a near-native English speaker, currently available, and results oriented - I am a freelancer, which requires little to none supervision to deliver.
I can modify the query quickly, using some or all of these T-SQL native functions: LAG, LEAD, ORDER BY, and some temporary tables. It shouldn't take more than two hours. You can contact me to help you.
