About

With a background in Mathematics and Advanced Statistics, I specialize in transforming raw, messy datasets into clean, automated, and actionable insights. Whether you need to sync your e-commerce data to a database or build an end-to-end ETL pipeline, I bring technical precision and "Zero-Blabla" efficiency to every project.

What I can help you with:

  • ETL Pipeline Development: Automating data collection, cleaning, and loading using Python (Pandas, SQLAlchemy).

  • Database Management: Expert SQL (PostgreSQL, MySQL) for complex querying, ranking, and data structuring.

  • Business Intelligence: Creating interactive Power BI dashboards that tell a story and guide your decisions.

  • IT Automation: Python and PowerShell scripting to automate repetitive tasks and optimize your workflow.

Why hire me?

  • Mathematical Accuracy: My Master’s level math background ensures your data is statistically sound and your metrics are accurate.

  • Google Certified: Professional certification in both Data Analytics and IT Support.

  • Efficiency First: I focus on scalable code and automated systems so you don't have to do the same work twice.
