Sai Samir

I am a Senior Data Engineer with ~6 years of experience building large-scale data pipelines, lakehouse architectures, and production ML/RAG systems using Spark, Databricks, AWS, and modern MLOps tools. I have delivered high-throughput Spark/Scala pipelines processing billions of records, implemented CDC and incremental ingestion, and built semantic/data-mart layers to enable self-service analytics and reliable reporting.

I combine strong engineering rigor—CI/CD, observability, IAM governance, and performance tuning—with applied ML and GenAI experience, designing RAG pipelines, vector search, and LLM microservices to accelerate data discovery and automation. My work includes migration of legacy warehouses, implementing Delta Lake best practices, and securing regulated healthcare and finance workloads to meet compliance and operational SLAs.
