About

Who I am

I work across the AI and data stack: designing ETL pipelines and lakehouse-style data layers, building Power BI and SQL-driven reporting, and shipping LLM products with RAG, vector search and agentic workflows. My focus is the unglamorous part that makes systems real — clean data, validated pipelines and reliable deployments.

Good AI starts with good data. I build both ends of that pipeline.
