Hi, I'm Jijo James 👋

Data Engineer specializing in building scalable data pipelines and LLM-powered applications.

About

I'm a Data Engineer passionate about building robust data infrastructure and leveraging Large Language Models to solve complex problems. I specialize in designing scalable ETL pipelines, data warehousing solutions, and AI-powered applications.

When I'm not architecting data systems, you'll find me experimenting with the latest LLM frameworks, exploring new technologies in the data space, or writing about data engineering best practices. Outside of work, I enjoy hiking, rock climbing, running, reading fiction, and exploring movies and gems on YouTube.
