I’m Chandrika, a storyteller with a passion for data. I thrive on transforming raw data into narratives that drive decisions, whether it’s through modifying data via ETL pipelines, crafting machine learning models, or predicting trends with time series forecasting. My journey also involves designing DLP rules, identifying vulnerabilities in infrastructure, and ensuring data stays secure. But it’s not just about the numbers, I love collaborating with people, learning from every interaction, and growing through shared experiences. For me, data isn’t just work; it’s a way to connect, create, and innovate.
