Powering AI with Data Modernization: ETL Using Databricks & Unity Catalog
**Title**: Powering AI Through Data Modernization: Modernizing ETL with Databricks & Unity Catalog
In this session, we will discuss how enterprises are modernizing their data platforms by migrating from legacy ETL tools (such as Informatica and traditional data warehouses) to Databricks Lakehouse architecture, and how Unity Catalog enables enterprise-grade governance, security, and discoverability across data and AI assets.
We will start with food and drinks at 6pm and then move into the presentation at 6:30pm.
The session will cover:
* Why traditional ETL platforms are becoming a bottleneck for scale, cost, and AI adoption
* How Databricks changes the data engineering and analytics operating mode
* The role of Unity Catalog in centralized governance
* How this foundation enables AI and Gene.AI use cases on trusted data
* Q&A
Our speaker for this event is **Hirenkumar Dholariya**.
Hirenkumar Dholariya is a Senior Data Engineering Architect with 18+ years of experience modernizing enterprise data platforms for global Fortune 500 organizations, delivering up to 40% system performance improvement and 20–35% infrastructure cost reduction through large-scale migration from legacy ETL platforms to cloud-native Lakehouse architectures. He specializes in Databricks-based data engineering, Unity Catalog–driven governance, and building scalable, secure, and real-time analytics platforms.
He has led multiple enterprise-wide transformations from tools such as Informatica and traditional data warehouses to Databricks, establishing governed data foundations using Unity Catalog and enabling advanced analytics and AI use cases on top of trusted data platforms. His leadership focuses on architecting durable data platforms, enabling teams to move faster with confidence, and translating data and AI investments into measurable business outcomes.

Native Plant Book Club: Animal, Vegetable, Miracle
Join our partners Watermark Woods Native Plants, Loudoun County Public Library (LCPL), and Birch Tree Bookstore for the Read! Plant! Grow! Book Club, which focuses on native plants, sponsored by Loudoun Wildlife Conservancy and LCPL. At this meeting we’ll discuss the book Animal, Vegetable, Miracle by Barbara Kingsolver. Both memoir and journalistic investigation, this book explores how the Kingsolver family took on a new challenge: to spend a year on a locally -produced diet, paying close attention to the provenance of all they consume. Concerned about the environmental, social, and physical costs of American food culture, they hoped to recover what Kingsolver considers our nation’’s lost appreciation for farms and the natural processes of food production.
You can either buy the book from Birch Tree Bookstore or contact Allison Forbes at [Allison.forbes@loudoun.gov](mailto:Allison.forbes@loudoun.gov) to borrow a copy of the book at the library. There are two ways to participate: attend the event online via the library website or [sign up to participate in person at Birch Tree Bookstore](https://www.birchtreebookstore.com/event-details/read-plant-grow-2026-02-24-18-30).
