About

I am a Senior Generative AI Engineer at Quantaco Technology, working on production systems for document understanding, invoice extraction, structured data generation, and accounting automation.

My work sits between backend architecture and applied AI: FastAPI services, OCR, embeddings, vector databases, Neo4j, LangChain, LangGraph, GraphQL, GCP, observability, validation, and reliable deployment.

Before this I worked as an AI/ML research fellow after a PhD in Mathematical Physics. That research background now sits underneath the engineering work: modelling structure, reasoning over knowledge graphs, and making AI systems auditable.
