I'm a Data Analyst and Educator based in Bengaluru, building at the intersection of data skills and data education.
With real internship experience at ElevanceSkills and Bluestock, I've analysed over a million records, built dashboards, and solved business problems with SQL, Python, and Excel. Outside of work, I run DATA DECODED โ a LinkedIn newsletter teaching the exact skills that get you hired as a data analyst.
My content has crossed 2 million impressions because I don't just explain concepts โ I make them impossible to forget.
