Message

At Preciso, I architect and maintain a Delta Lake on Databricks, bringing fragmented data from BigQuery and Pub/Sub together. I also develop automated ETL schedules and data catalogs to prepare data for analysis and future initiatives.

As a Data Analyst at Preciso, I led a project to extract user profile features and identify buying intentions and consumer patterns. I applied RFM analysis to segment high-value audiences for marketing retargeting.

At Digital University Kerala, in collaboration with Preciso, I worked on ad-tech data analysis and multi-source data processing. I researched outlier detection and developed NLP-based summarization methods, using Python to support data preprocessing and analytical pipelines.
