## Headline

Software Engineer @ Epsilon India \| Azure Databricks \| Azure Data Factory \| PySpark \| SQL \| Data Pipelines \| GenAI & AI Agents

## About

I’m a Data Engineer with 4 years of experience building scalable data pipelines and cloud\-based data solutions using Azure Databricks, Azure Data Factory, PySpark, Spark SQL, Python, and SQL\. My experience spans the complete data engineering lifecycle — from understanding legacy data workflows and upstream/downstream dependencies to designing modern data architectures, developing transformation pipelines, validating data, and optimizing processing\. In my current role, I’ve worked on customer data modernization using Medallion Architecture and Unity Catalog, building curated datasets and behavioral features to support campaign response prediction and downstream analytics\. I’ve also explored the intersection of Data Engineering and Generative AI, developing an AI\-driven QA validation agent using LLMs, LangChain, LangGraph, multi\-agent workflows, and n8n to automate validation and human\-review processes\. Earlier in my career, I built a database foundation through SQL/PL\-SQL development, performance tuning, ETL, automation, and data validation, including an in\-house audit reporting solution that achieved 100% cost savings\. I enjoy solving complex data problems, modernizing legacy processes, and building reliable solutions that turn data into something teams can actually use\.
