PGS SOFA & COSeptember 2013 - June 2016

During this time period i worked as a VBA/SQL developer.
Achievements:
VBA: wrote apps for various departments such as logistics, hr, production, controlling, accounting etc. . The VBA code implied excel Forms, flat file exports, inserting data into a SQL Server DB, hard-copy prints, warehouse stock analysis etc.
SQL:
I was tasked with maintaing the Reporting Server. It ran a SQL Server 2008R2 Standard edition. Wrote reports that used add-hock queries, views, stored procedures, jobs, SSRS, Power BI.
As far as SQL Server Reporting Services goes i used it a lot of times, as most of the presentation to the end user was done via it. Mostly i created reports with hard-coded SQL, but i am not a stranger to SSRS reports that trigger stored procedures on a click.
Successfully implemented a DW. Advanced knowledge of SSIS.
Other tasks i used to ran on the reporting server were database maintenance tasks such as index and statistics maintenance
