I’m a results-oriented data professional focused on transforming raw data into reliable, scalable systems that enable smarter decisions. I build ETL/ELT pipelines, optimize SQL for faster analytics, and turn datasets into clear BI dashboards.

In my current role as a Trainee Consultant, I designed and optimized SQL queries and data pipelines, reducing data retrieval time by ~30%. I built end-to-end ETL workflows with Python-based preprocessing and MySQL for structured reporting, and I implemented Retrieval-Augmented Generation (RAG) workflows to improve contextual response accuracy for domain-specific queries.

I also create data solutions that reduce manual effort and improve insight quality. I developed an automated entity-resolution tool using NLP-driven name matching across 5,000+ records, cutting manual lookup effort by ~40%, and I applied clustering (K-Means and Hierarchical) to improve data segmentation and insight generation by ~25%.

Previously, as a Data Analyst Intern, I analyzed 10,000+ real-time data points using Python, SQL, and Excel, and built 15+ visualizations with Matplotlib, Seaborn, and Excel dashboards. I’m driven by practical impact—winning Top 10 of 75+ teams at a national healthcare hackathon for a 36-hour data prototype and leading event operations as an Anchor & Coordinator.
