David Papp
AI engineering student at VU Amsterdam, building production-quality tools for the LLM stack. I focus on the infrastructure between models and users — observability, guard rails, fine-tuning pipelines, and retrieval systems.
Background
I consulted for an AI-first startup where I restructured their LLM backend to cut unnecessary OpenAI API calls by ~40% and closed a prompt injection vulnerability in their moderation layer. I consistently take the technical lead role in hackathon and rapid-build teams of 4–5 people.
Before university, I worked as a Project Assistant at 4iG (Budapest) on two large public-sector IT projects, and taught programming at Logiscool.
