👋 Hi, I'm Dennis Njiru Aningu — a self-taught Data Analyst passionate about uncovering insights from data and helping teams make smarter decisions.

🔍 I specialize in:

  • Writing complex SQL queries (Snowflake, Metabase)
  • Building interactive dashboards (Power BI, Tableau)
  • Automating reports and workflows (Excel, Python)
  • Cleaning and transforming data for analysis (ETL)

📊 I enjoy solving real-world problems with data and creating dashboards that tell compelling stories. I'm always looking for ways to optimize reporting, improve decision-making, and make data more accessible.

🎯 On GitHub, you’ll find:

  • Sample dashboards and SQL projects
  • Python scripts for data cleaning and analysis
  • Personal learning projects as I grow in Power BI and Python

📚 Currently learning: Advanced Power BI & Python for Data Analysis 💬 Let’s connect or collaborate — always open to learning and sharing!
