As a Freelance Data Analyst, I standardize reporting architectures and documentation for client data sources, helping keep metrics reproducible and maintainable.

I engineer SQL views with CTEs, conditional logic, and row-number deduplication to sanitize noisy real-world data logs. I also structure activity logs from PHP web applications for analytical reporting.

In my cloud data warehouse project, I provisioned PostgreSQL on Aiven and designed a star schema connected to Power BI. DAX metrics provide automated KPI insights.

I’ve also developed Python data-cleaning and exploratory analysis workflows, including one that reduced recurring reporting overhead by 75%, and an Excel model examining discounts and customer satisfaction.
