Nida Kapmaz

I’m a Data Analyst and BI Specialist with 5+ years of experience designing real-time dashboards, building scalable ETL pipelines, and delivering data-driven insights to 400+ global clients across 15+ countries.

I’ve delivered 150+ dashboards and processed 5B+ daily data records across FMCG, Fintech, Smart City, Telecom, and Retail, translating complex raw data into clear, decision-ready analytics. I work comfortably across SQL and Python (Pandas, NumPy, cuDF) and leverage Apache Superset, Tableau, and Power BI to present results with impact.

On the engineering side, I focus on reliable data flows for real-time analytics—engineering ETL pipelines with Python and Apache Druid at scale, plus strong data cleansing and transformation. I also apply geospatial analytics with geohashing, GeoJSON polygon extraction, and interactive map visualizations (including Kepler.gl) to turn location data into actionable outcomes.

Equally important, I’m the technical liaison who gathers requirements and aligns stakeholders through clear, asynchronous communication. I’ve built audience datasets for advertising campaigns using geohashing and location APIs (Google Places, Overpass) and segmented 200,000+ customer profiles by income, age, gender, and behavioral data—bridging sales needs with technical solutions from specifications to delivery.
