About

I build search system that don't just find data - they understand it. Currently, I’m re-imagining the Search Platform at AlphaSense, merging Vector Search with RAG to power deep market intelligence. Previously at MediBuddy, I learned that scale is nothing without efficiency—scaling the InsureTech product by 900% while slashing cloud costs by 60%. I specialise in: - AI Engineering: RAG, LLMs, Vector Databases (Vespa, Solr). - Leadership: Taking teams from chaos to delivery. - Scale: Handling high-throughput systems with 99.9% uptime.
