I've built ETL pipelines at TEK YANTRA using Python and SQL, extracting, transforming, and loading data from multiple sources into relational databases. I also optimized SQL for extraction, validation, and reporting to improve data accuracy and query performance.

At Cognizant, I developed practical data-processing and analytics skills across Python, SQL, PySpark, ETL, data warehousing, and cloud fundamentals. I've applied feature selection and feature engineering to prepare higher-quality datasets for machine learning models.

My Bengaluru digital twin project integrates municipal and geospatial datasets to model infrastructure demand, forecast city-scale needs, and support resilient allocation planning. I used statistical, clustering, machine learning, and deep learning approaches including OLS, K-Means, LightGBM, LSTM, and Temporal Fusion Transformers.

I've also analyzed Telangana registration, vehicle sales, and investment data to surface regional trends and policy recommendations. As Documentation Lead for the Atharva Data Science Community, I organized workshops, seminars, and hackathons for a 700+ member student community.
