About

I build data systems that actually make it to production — and AI layers on top of them that deliver real business value. At Tata Consultancy Services, I work across the full stack of modern data & AI engineering: designing Medallion Architecture pipelines on Databricks, engineering Snowflake data warehouses, and building LangChain-powered agentic workflows. My work spans both sides of the stack — clean, reliable data infrastructure and intelligent AI systems on top of it. On the Data side, I've migrated 240+ GB of enterprise data into Azure Data Lake, built watermark-based incremental ETL pipelines with ADF, and cut BI query times by ~30% through Snowflake schema optimization and clustering strategies. On the AI side, I've delivered production agentic workflows for a US healthcare client (Humana) — including a FHIR appointment booking agent with multi-step tool calling, a .NET Package Upgrader Agent, and a RAG-based clinical NLP system using LangChain and Azure OpenAI. The GenAI POC earned me the TCS Warrior Award. I've also built cross-cloud healthcare pipelines connecting GCP BigQuery → Databricks → Snowflake, feeding patient risk stratification models. Certifications: Databricks Data Engineer Associate · Databricks GenAI Developer Associate · Microsoft AZ-900 · AI-900 📍 Noida, India · Open to Data Engineer, AI/ML Engineer, and GenAI Developer roles — India or remote/global opportunities.
