Karthikeya Doppalapudi

I’m a Data Analyst with experience analyzing and managing large datasets, creating reports and dashboards, and supporting data-driven decision-making. In my current role at Tata Consultancy Services (Apr-2024 - Present), I designed and built responsive Angular interfaces and connected them to backend services through APIs for seamless data exchange and real-time updates. I craft efficient SQL queries using joins, aggregations, and subqueries to power business reporting, and I build interactive Power BI dashboards to visualize insights. I also focus on data optimization—processing high-volume data and improving performance through query tuning strategies. From a normalized MySQL database project to implementing stored procedures, indexing, and plan analysis for faster access, I consistently aim for accurate data handling and efficient, user-friendly applications.
