IcelandWhat I'm looking for
I’m a Data Analyst with 8+ years of experience in data management, analytics, and business intelligence, focused on turning raw data into measurable outcomes. I build SQL-driven reporting, design and maintain relational data models, and deliver KPI visibility through Power BI dashboards that support better decision-making.
In my recent work as an IT Systems & Data Specialist, I designed ETL pipelines consolidating multi-source data to improve consistency and accuracy, then processed and analyzed datasets with Python (pandas) for cleaning, transformation, and EDA. I also automated reporting workflows using Excel and Python—reducing manual workload—and integrated external APIs (n8n, Zapier, OpenAI API) to enrich datasets and automate pipelines, while collaborating with stakeholders to gather requirements and improve reporting processes.
