Aziz Ishan-Khojaev Data Engineer and Analyst

Why should you work with me ?

I’m a Data Analyst and SQL specialist focused on turning raw, messy data into clean, structured, and high-value information.

I work with businesses, researchers, and teams who need their data cleaned, organized, and ready for real use — whether that means analytics, reporting, or database integration. I specialize in SQL, data processing, and performance optimization, and I’m comfortable working with large datasets containing hundreds of thousands or even millions of rows.

What I do best:

• Writing and optimizing complex SQL queries

• Cleaning and standardizing messy datasets

• Removing duplicates, fixing inconsistencies, and improving data quality

• Processing large datasets using Python (pandas & polars)

• Preparing data for analysis, dashboards, and SQL databases

• Building efficient workflows that save time and reduce manual work

I focus on accuracy, speed, and clear communication. My goal is not just to deliver a file, but to deliver reliable data you can confidently use for decision-making.

If your data feels overwhelming, unstructured, or too large to handle efficiently — I’m here to help.
