UMAMAHESWARI NAGALINGAM

Data Analyst | Amazon Alum | M.Sc. Data Science & AI I thrive at the intersection of product, engineering, and business logic. With 2.5 years of experience at Amazon and a Master’s in Data Science & AI from GISMA University, I specialize in transforming massive, raw datasets into scalable analytical foundations. My approach is simple: Data is only as good as the decisions it enables. At Amazon, I re-engineered SQL workflows for catalogs exceeding 4M+ rows, saving over 15 manual hours per week while ensuring 100% data integrity. I am an expert in the SQL + Python + Power BI stack, with a deep interest in Analytics Engineering (dbt) and AI-enabled automation. Core Expertise: 📊 BI Development: Building high-impact dashboards (Power BI/Tableau) that define and track commercial KPIs. ⚙️ Data Engineering: Optimizing ETL/ELT pipelines and BigQuery environments for maximum performance. 🎯 Product Analytics: Translating complex stakeholder needs into technical data models that drive growth. 🤖 Advanced Analytics: Applying my research in Agentic AI and ML pipelines to solve real-world automation challenges. I am currently based in Berlin and eager to contribute to a data-driven team where I can build end-to-end analytical solutions. Technical Toolkit: SQL (Advanced), Python (Pandas/NumPy), BigQuery, Power BI, Tableau, ETL/ELT, Git. 📍 Based in Berlin | 📢 Open to connections and new opportunities in Data/BI/Analytics Engineering.
