What I'm looking for

I’m looking for a role where I can build and optimize ETL pipelines, write strong SQL for data extraction and reporting, and create Power BI/SSRS dashboards—using Python for data quality and automation to support analytics, forecasting, and process optimization.

I’m a Data Engineer & Data Analyst with 4+ years of experience in ETL, SQL, and BI development, turning business needs into data-driven solutions. I’ve focused on e-commerce analytics, forecasting, and process optimization for teams like L’ORÉAL CZECH REPUBLIC—building pipelines, extracting and transforming data, and ensuring data quality.

In my roles, I write and optimize SQL queries, build and maintain ETL pipelines using Informatica and SQL Server Integration Services (SSIS), and deliver reporting through SQL Server Reporting Services (SSRS) and Power BI dashboards. I also use Python (pandas, NumPy) to automate workflows, run data quality checks, and improve reliability by resolving data issues quickly.
