Data & AI Engineer at Airbus, building LLM-based quality analysis systems and ML pipelines for the A330/A350 programs. GCP Professional Cloud Architect & Data Engineer certified.

I work at the intersection of data engineering and AI, from data pipelines to fine-tuned LLMs to GenAI products, all in service of one thing: making data useful.

Outside of work, I build CraftCourse, an AI-powered learning platform with 500+ users.
