Position: SQL developer
Category: SQL
English level: basic
Years of experience: 11

Someone born as a developer, someone starts learning at the University. As for me, my achievement is that I reloaded all my knowledge at the age of 50 and started learning SQL. So now, SQL and script-building - it's my passion.
For the last 10 years, I have been working in a Ukrainian telecom company as the Chief Specialist in the Analysis and Reporting Department position. I worked with a vast DB, more than tens of millions, for these years. 

Main tasks: 

- Development and maintenance of the accounting system's up-to-date statistical and reference information based on the Oracle database.
- Creation, refinement, and testing of SQL queries and procedures in the Oracle database for both new and existing regular analytical reporting
- Formation of one-time ad-hoc samples (SQL samples, PivotTables, etc.) with internal and external queries in various sections, based on data from the Oracle database.
- Checking the completeness and correctness of data in the source tables and directories of the Oracle database.
- Development and preparation of regular internal and external analytical and statistical reports in Excel format on sales of services, services, and financial indicators. Automate retrieval of Oracle DB and required reports by writing views.
- Setting requirements for IT departments to automate and optimize the processes of formation and preparation of reports.

For now, I'm looking for a new role and position for my career as a SQL developer/programmer or SQL DB tester.
