About David
Ingénieur spécialisé en intelligence artificielle et en traitement automatique du langage, je développe des solutions d’IA générative. Mon expertise couvre la conception de systèmes de NLP industriels, l’optimisation de la recherche d’information et le déploiement d’applications d’IA à grande échelle. Passionné par l’état de l’art en IA, je combine recherche scientifique et mise en production de solutions intelligentes.
Ma démarche repose sur une méthodologie itérative, favorisant le passage rapide du POC à la production en respectant les meilleurs standards de qualité logicielle et d’ingénierie des systèmes d’IA.
