About

I’m a seasoned data engineer with 12 years of experience in data warehousing and data governance across large-scale e-commerce environments. Currently, I’m actively exploring the intersection of big data and AI—building LLM-powered assistants for data discovery, metric explanation, and self-service SQL generation using GPT-4o and RAG architecture. Passionate about turning complex data into trusted, reusable assets—and making data more intelligent, accessible, and efficient for everyone.
