About Me
I'm a Data & Business Analyst based in Chennai/Bangalore, building data pipelines and dashboards that operations and leadership teams actually use. My foundation in Mechatronics engineering shapes how I approach both software and hardware problems — from ETL pipelines to a self-built electric skateboard.
Currently targeting Business Intelligence Engineer and Data Engineer roles, with experience spanning catalog operations at Amazon, IoT analytics at Altizon, and AI model evaluation at Turing.
