Freelancer Overview

I’m a Data Analytics graduate with a Master’s in Computer Applications (Data Analytics) from Jain University, where I graduated with a CGPA of 8.69. I have a strong foundation in SQL, Power BI, Python, and data engineering tools such as Kafka, Airflow, DBT, and Snowflake. I’ve worked on end-to-end analytics projects ranging from real-time data pipelines using the modern data stack to business-focused dashboards analyzing customer behavior and operational performance. In addition to analytics projects, I have freelance experience as a data annotator, where I contributed to training AI and LLM models. My work involved annotating and reviewing data for image, video, and website generation tasks, count verification, and writing and reviewing high-quality prompts to ensure model accuracy and consistency. I enjoy transforming raw data into actionable insights and working at the intersection of data analytics and AI. I’m now looking for an opportunity where I can contribute to data-driven decision-making while continuing to grow as a data professional.
