Tetiana Omelchenko

I'm currently developing Microsoft SQL Server database infrastructure and ETL architecture for maanto's campaign management and reporting SaaS platform in Cologne. I also support stable application operations and contribute to Azure DevOps CI/CD processes and automated reporting documentation.

At Diezel&Co on a Deutsche Bank Threat Center project, I maintained a security data warehouse spanning 12 databases, 11 OLAP cubes, and 1,500+ database procedures and functions. I added four ETL pipelines and three application modules, improved processing efficiency by up to 25%, and reduced UI query runtime by 40%.

I've supported analytical platforms in banking and healthcare, translating requirements from multiple departments into data structures, reporting, and dependable data flows. I maintained 99.9% system availability in a regulated banking environment and provided L3 support for more than 100 users.

Earlier, I led full-cycle BI projects at VisiQuate and built database objects and SSRS reports for Team International. I'm continuing to deepen my cloud data engineering skills through Databricks, Apache Spark, AWS, BigQuery, dbt, Airflow, Docker, and Terraform projects.
