What I'm looking for

I’m looking for a data-focused role where I can build dashboards, automate reporting workflows, and apply SQL/Python statistical analysis to solve real business problems while growing in a collaborative environment.

I’m a Computer Science graduate and Data Analyst with hands-on experience using SQL, Python, Power BI, and Excel to clean, analyze, and visualize data. I focus on building interactive dashboards and applying statistical analysis to solve business problems, turning complex results into clear, actionable insights.

I’ve delivered training as a Project-Based Data Analysis & Python Instructor and built real projects like a Power BI sales performance dashboard for 50,000+ records, using Power Query to automate refresh workflows. I also analyzed 7,000+ telecom records to identify a high-risk churn segment (73.5% churn rate) and performed A/B testing on 588K+ records using Z-test analysis to support marketing decisions.
