What I'm looking for

I seek a data-focused role where I can build dashboards, automate reporting, and turn data into clear insights for business decisions while growing my analytics and BI skills.

I am a data analyst with 2+ years of experience building dashboards and performing analysis using Excel, Power BI and SQL. I focus on cleaning, transforming and validating data to improve accuracy and create interactive reports that surface KPIs, trends and performance insights for non-technical stakeholders.

As a Computer Engineering (B.Eng) graduate, I have automated recurring reports to increase efficiency and written SQL queries for joins, aggregations and filters. I combine technical skills (Power BI, DAX, Excel, SQL) with analytical thinking and communication to drive data-driven decision making.
