Rockstar🎓
Top SchoolThomas Queste is a pragmatic technical lead with ~20 years of software experience and a 15-year track record of building large-scale, production search systems and AI-enabled product experiences. At ADEO he led development of Leroy Merlin’s search platform—scaling catalogs 45x, improving CTR to ~42%, and running hundreds of queries per second with high availability—then moved into integrating VertexAI, RAG, and vector search to bring natural language and question-answering into production. Product-minded and operator-focused, he combines ranking science, knowledge-graph entity recognition, and performance-first engineering with tooling like a custom Elastic operator and a Relevant Workbench CLI for measuring nDCG impact. A serial founder and certified specialist in Elasticsearch, MongoDB, ML and Java, he mentors teams on relevance, prompt engineering, and shipping fast while contributing to open-source back-end tooling such as cozy-stack. Based in Lille, he pairs hands-on coding in TypeScript and Python with a pen-and-paper obsession for clear design and practical trade-offs.
