What I'm looking for

I'm interested in LLM/agentic data workflows.

At Sigmoid, I maintain multi-tenant ETL/ELT pipelines for pharma sales data across global markets using Azure Databricks, PySpark, Delta Lake, and Azure Data Factory. I built a declarative data quality framework with automated record quarantine, run-metrics logging, and alerts.

At National Institute of Technology, Kurukshetra, I built a smart toll pipeline using YOLOv8, EasyOCR, and Streamlit, achieving 97.57% mAP@50. I’ve also built an agentic data-quality workflow with LangGraph and a learning-platform analytics project using Microsoft Fabric.
