About Me

Peri Venetis

I’m Peri, a Computer Science graduate turned data analyst with hands-on experience in SQL, Power BI, and Python. I help organizations make sense of their operational and customer data to drive smarter decisions.

My approach combines structured data cleaning, exploratory analysis, and actionable visualization. I’ve completed projects that span market analysis, customer segmentation, and operational insights — always focused on turning raw data into clear, decision-ready insights.

I’m seeking opportunities to contribute as a data analyst, leveraging strong technical skills and analytical thinking to help teams understand their data, uncover trends, and make impactful decisions.
