Data Analyst & SQL Developer | Data Cleaning, Dashboards & Automation

Stop losing time with messy spreadsheets and start making data-driven decisions.

I am a Data Analyst specializing in transforming raw, chaotic information into streamlined systems and professional visual reports. Whether you have a broken Excel file or need a full SQL database architecture, I provide clean, scalable, and secure solutions.

What I can do for you:

Data Cleaning & Automation: I use Python to clean, format, and normalize complex datasets (Excel/CSV).

Business Intelligence: I build interactive dashboards in Looker Studio and Power BI that turn numbers into clear insights.

Database Architecture: I design and migrate data to robust SQL structures (PostgreSQL/MySQL), ensuring data integrity and security.

Why work with me? I don't just "move data." I audit its integrity. I recently led a full-scale data migration for an NGO, moving their entire financial management from static Excel files to a relational PostgreSQL system.

My tech stack: Python (Pandas), SQL (PostgreSQL), Looker Studio, Power BI, and Data Security (Masking).

Got a project in mind? Send me a message, and let’s discuss the best way to organize your data.
