What I'm looking for

I’m seeking a data analyst role using Excel, SQL, Power BI and Python to deliver actionable insights, optimize costs, and support data-driven decisions within collaborative, growth-oriented teams.

I’m not just a Data Analyst. I believe data should do more than fill dashboards. It should tell stories, uncover problems, and drive smarter decisions. With expertise in Power BI, Excel, SQL, and Python, I enjoy transforming raw, messy data into insights that reveal hidden patterns, risks, and opportunities. My goal is simple: to bridge the gap between data and business by making complex findings clear, actionable, and impactful.

What I do best

▪️Turning messy datasets into clean, reliable information

▪️Build dashboards that tell the why, not just the what

▪️Use SQL & Python to dig deep into data and uncover hidden opportunities

▪️Apply Excel & Power BI to track KPIs and automate reporting

▪️Communicate insights in a way that inspires action

▪️Databases: PostgreSQL

▪️Visualization: Power BI, Excel (Power Query, Power Pivot, VBA)

▪️Programming: Python (Pandas, NumPy, Matplotlib, Seaborn)

▪️Productivity: MS Office Suite (Word, PowerPoint, Outlook), Jupyter Notebook

What I Deliver:

▪️Insights that highlight not just numbers, but the stories behind them

▪️Interactive dashboards and reports that spark decision-making

▪️Data-driven recommendations that improve efficiency and cut costs

▪️A problem-solving mindset that connects data with real-world business needs
