Cloud Data Platforms·Lakehouse & GenAI·AWS·Snowflake·Databricks
I design and build data platforms that scale — and increasingly, that think. Over 10+ years in big data engineering and cloud architecture, I now focus on Databricks Lakehouse builds, production MLOps pipelines, and GenAI/LLM solutions (RAG, copilots, applied AI) layered on top of the data foundations I've spent my career architecting. Currently a Senior Lead Architect/Engineer at NTT DATA UK&I, delivering platforms across banking, insurance, and airline sectors.
