Are you looking to turn your raw sales, revenue, or business expense data into clear, actionable insights? You are in the right place!

I am a data analyst specializing in data cleaning and financial data analytics using Python and SQL. I will help you fix messy records, extract key metrics, and visualize your business performance.

What I Can Do For You:

  • SQL Querying: Write efficient custom queries to filter and extract data from your PostgreSQL/MySQL databases.
  • Data Visualization: Create clear charts (line, bar, pie) using Matplotlib and Seaborn to easily spot business trends.

Why Choose Me?

  • 100% Data Confidentiality: Your financial and business data will be handled with strict privacy and secure deletion after project completion.
  • Clean Code: Deliver well-documented Python scripts or Jupyter Notebooks that are easy to understand.
