I’m an aspiring data analyst focused on using SQL, Python, Excel, and Power BI to deliver clear reporting, visualization, and data-driven decision support. With training from my B.Tech in Artificial Intelligence and Data Science and multiple data-analytics job simulations, I’ve built a strong foundation in applied data work.

In my internships, I’ve done text data annotation and quality validation for AI/LLM training datasets and performed LiDAR frame data annotation to support AI/ML dataset preparation. I also develop practical machine learning solutions—like a face detection application using Python and OpenCV and an IoT-based flood prediction system using RF communication and K-Nearest Neighbors (KNN)—with an emphasis on accurate preprocessing, validation, and results.
