What I'm looking for

I'm looking to build production AI systems where evaluation, cost-efficient inference, compliance, and measurable customer impact matter. I value opportunities to lead teams, mentor engineers, and deliver reliable LLM and full-stack products.

At Skyscanner, I built RAG and GraphRAG pipelines serving 100M+ monthly queries, increasing retrieval hit rate from 82% to 87% and reducing hallucinations by 40%. I also deployed travel-personalisation reasoning agents, fine-tuned Llama 3 and Mistral 7B to save roughly $18K monthly in inference costs, and led a pod of eight engineers.

Previously at Fenergo, I productionised LLMs for KYC/AML document extraction and built regulatory RAG and evaluation systems used by compliance teams. My full-stack foundation spans Python, .NET, React, AWS, and reliable delivery practices, from microservice migrations and Terraform infrastructure to EU AI Act auditability.
