Summary
👤
Senior🎓
Top SchoolGuillaume Dessain is a Solutions Engineer Manager based in Paris with 10 years of hands-on software and automation experience, currently leading SMB and Mid-Market SEs at Algolia. He blends technical leadership, player-coach execution, and product-minded engineering to design LLM-ready search and RAG architectures that prioritize relevance, speed, and simple operational models. Guillaume grew the SMB SE function from a single contributor to a team of five while centralizing solution patterns and evaluation paths to scale repeatable outcomes. He’s equally comfortable deep in backend prototyping and debugging—his open-source contributions include backend fixes for the popular Cassiopeia Python framework for Riot Games’ API, showing a taste for data-focused, game-related tooling. Colleagues rely on him to turn opaque problems into clear plans and production-ready systems, and he’s driven by building things that ship and teach others along the way.
