I’m a data analyst building dashboards and pipelines with SQL, AWS QuickSight, and automation.

What I'm looking for

I’m looking for a role where I can build reliable data pipelines, deliver KPI dashboards in AWS, and own data quality and automation—working with large datasets and stakeholders to continuously improve analytics and reporting.

I’m a data professional with experience working with large-scale datasets in SKILLS data operations and analytics environments at Amazon. I focus on data pipeline reliability—ETL processes, data quality assurance, and reporting—so teams can trust the KPIs they make decisions on.

In my current role as a Data Analyst / Data Management Engineer (ML Data Associate III) at Amazon Development Center Poland sp. z o. o., I’ve supported complex data analysis and built analytical dashboards and reports in AWS QuickSight. I’ve also developed Python automation scripts for data analysis, helping scale validation, task creation, and dataset delivery workflows.

Previously, I processed and analyzed datasets containing up to 9 million videos and managed annotation tasks for 300+ annotators, ensuring timely project delivery and improved accuracy through root cause analysis. I’m currently focused on strengthening my skills across data analytics, BI, and data engineering, while continuing to build strong dashboards and data pipelines.
