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).

Portfolio

Processed and consolidated years of decentralized, messy records into a single, structured "source of truth." Using advanced technical workflows, I eliminated thousands of duplicates, fixed inconsistent formatting (dates, currencies, names), and ensured 100% data integrity for a non-profit organization.
Key Outcome: Transformed chaotic spreadsheets into a professional, audit-ready dataset.
Developed a comprehensive Business Intelligence solution using Looker Studio, Excel/Sheets and Power BI. I transformed complex financial data into interactive dashboards with real-time KPI tracking, dynamic filters, and automated reporting.
Key Outcome: Enabled the organization’s management to make data-driven decisions in seconds, replacing hours of manual report generation.
Engineered a robust relational database system from scratch to replace obsolete static storage. I designed the full Entity-Relationship Diagram (ERD), implemented PostgreSQL architecture, and managed the secure migration of historical data with zero loss.
Key Outcome: Established a professional, scalable infrastructure that ensures data consistency, security, and high-performance querying for years to come.
