Freelance Data Analyst turning multi-source location data into documented, quality-checked datasets and reports.

Turkey
Message

As a Freelance Data Analyst, I collect, clean, match and report on data using Python, SQL and public APIs. I built a store-locator scraper that extracted 244 locations and produced CSV and GeoJSON files with duplicate checks and automated tests.

For a data and operational analytics project at IBRIK, I analyzed more than 30,000 customer, reservation and sales records from Zenchef and Addition. I gathered management requirements, defined KPIs and created reports and dashboards to support operational decisions, targeted marketing and performance monitoring.

I also developed a multi-source location-data pipeline using SIRENE, OpenStreetMap and official geocoding. I documented its processing rules, data sources and quality checks, and reviewed uncertain matches.

My mathematical training and doctoral research at Université Paris 1 Panthéon-Sorbonne shaped how I frame complex problems and present findings. I bring that analytical background to business questions, working across French, English and Turkish.
