What I'm looking for

I seek roles where I can lead cloud-based ETL and BI migrations, craft scalable data models, and deliver clear visual analytics in collaborative Agile teams.

I am a Data Analyst and Analytics Engineer with over five years designing, optimizing, and maintaining data pipelines and BI environments. I focus on ETL processes, SQL data modeling, and migrating dashboards from Power BI, Tableau, and Qlik Sense to Amazon QuickSight.

At Zallpy Digital I led BI migrations to QuickSight, documented ETL transformations, automated metadata extraction via JavaScript and REST APIs, and built SQL data models in Athena and S3 to improve query performance.

Previously at Ericsson I monitored SLAs and KPIs, developed managerial dashboards in Power BI, automated data ingestion with Python consuming ServiceNow APIs, and trained teams on ITSM aligned with ITIL practices.

I combine cloud-native AWS skills with Python scripting, a passion for data visualization and storytelling, and practical experience in scalable analytics architecture to deliver actionable insights and reduce operational overhead.
