Hi, I'm Sundar Garimella 👋 I'm a Senior Software Engineer at Franklin Templeton, working as a Data Engineer and Lakehouse Architect. I'm Microsoft Certified in DP-600 (Fabric Analytics Engineer Associate) and DP-700 (Fabric Data Engineer Associate), and I specialize in building end-to-end Lakehouse solutions on Microsoft Fabric. My day-to-day work involves architecting Bronze/Silver/Gold Medallion pipelines, implementing Data Mesh principles at scale, and solving real-world data engineering challenges — from complex nested JSON parsing and Delta Lake schema management to OneLake security and Fabric REST API integrations. I currently work on financial data pipelines processing loan, forecasting, and prepayment data for institutional clients. I'm currently expanding into Microsoft Fabric Foundry and AI, and I'm active in the Fabric community, sharing practitioner-focused content on architecture and pipeline design. I can help you with: Microsoft Fabric Lakehouse architecture & design (Medallion + Data Mesh) DP-600 / DP-700 certification guidance and exam prep PySpark, Delta Lake, and Spark notebook development Fabric pipeline orchestration, data pipelines & ADF integration OneLake security, SQL analytics endpoints & access control Career guidance for Data Engineering roles in the Microsoft ecosystem Resume/profile reviews for Data Engineer / Fabric roles Whether you're prepping for your Fabric certifications, architecting your first Lakehouse, or navigating a career shift into data engineering — happy to share what I've learned building production-grade pipelines in the field.
