What I'm looking for

I seek roles where I can build and optimize ETL/analytics pipelines, deliver BI insights, work cross-functionally, and improve data quality in a collaborative, growth-oriented team.

I am a data analyst with hands-on experience in analytics engineering, ETL pipeline development, and BI reporting. I design and optimize data flows, manage data warehouses, and deliver dashboards and presentations that support strategic and marketing decisions.

My recent experience includes building ETL pipelines with Kleene AI, maintaining data warehouses, and creating Tableau dashboards to improve KPI tracking and data-driven decision-making. I also have a strong background in marketing analytics, A/B testing, and establishing data quality monitoring frameworks.

I bring cross-functional experience from technical support and incident management roles to ensure operational reliability and continuous improvement, and I focus on delivering trustworthy data, clear insights, and measurable business impact.
