Data Analyst at Flipkart building Python ETL pipelines and KPI dashboards to track operational performance.

India
Message

At Flipkart, I develop Python ETL pipelines to clean, transform, validate, and analyze operational datasets. I also build Power BI and Looker Studio dashboards to monitor business KPIs and operational performance.

I automated recurring report distribution with Python, Gmail API, and OAuth 2.0, reducing distribution time by 40%. My automation scripts also eliminated more than 15 hours of manual data-processing work per week.

In my projects, I developed a machine learning prediction application with a Flask interface and created a retail analytics dashboard covering revenue, product performance, and customer trends. I’m currently developing deeper expertise in Generative AI, including LLMs, RAG, embeddings, and vector databases.
