I'm Rajaram Yadav — a Data, AI, Software, and ML Engineer who builds systems that scale, perform, and hold up in production. I move fast on new stacks, ramp quickly on unfamiliar domains, and ship with confidence from day one.

From lakehouse pipelines and real-time data platforms to RAG architectures, microservices, and full-stack applications — I design end-to-end solutions across AWS, Azure, Snowflake, Databricks, Spark, Kafka, LangChain, Java, Spring Boot, and modern frontends. Give me a hard problem and a tight timeline — I'll deliver.
