Hi, I am Andalib Ansari, a Data Architect and AI Engineer with 12+ years building the data platforms that power some of the world's biggest online gaming, ride-hailing, SaaS, and telecom companies.

I have architected large-scale data lakes and warehouses processing petabytes of data, built high-performance pipelines with Spark, Airflow, and Python, and shipped production systems on Redshift, EMR, Athena, Hive, and Scala. More recently, I have moved up the stack - designing agentic AI applications and RAG assistants with LangChain and n8n that sit directly on top of the data platforms I build, turning raw pipelines into systems that actually reason and act.

I have delivered production-grade architectures across AWS and GCP, built analytics platforms and React-based data tools, and led engineering teams shipping real infrastructure with real business consequences.

Along the way, I have built two courses, from Big Data and Hadoop fundamentals for beginners to hands-on Data Engineering with SQL, ETL, PySpark, and AWS, reaching 29,000+ students across 145+ countries. These courses are the next step: practical, hands-on, and built for the modern data stack, the same tools and patterns I use in production today, distilled into a path that makes you genuinely job-ready.

If you are serious about breaking into data engineering or leveling up into the AI-powered future of the field, you are in the right place. Let's build something real together.
