I have been working as a Data Engineer/Business Intelligence Developer for about four years. My job is to translate business requirements to a complete report. I provide end to end development, testing and full support of the business data flows within a DWH and corresponding BI reporting atop of this data. This includes such steps as extracting data from production environment, cleaning, transforming and loading, performance optimization and, finally, building report atop of that data. I have strong knowledge and experience in the following technologies: - Tableau - Looker - Power BI - DBT - Rundeck - ETL - SQL - MySQL - PostgreSQL/Redshift - Hadoop/Hive - NoSQL - Cassandra - MongoDB - Data Warehousing - Data Visualization - Query Optimization, query profiling - AWS - Hubspot Reporting - Mode Analytics. Resuming above, I have strong skills in SQL, data visualization and have experience in report end to end development. Also I am extremely attentive to details, self-organized and very responsible.
