  • Développement front-end (interfaces modernes, ergonomiques et responsive)
  • Développement back-end (API, bases de données, architectures scalables)
  • Intégration de solutions de paiement comme Stripe
  • Conception d’agents IA sécurisés (LLM, workflows, intégration dans vos apps)
  • Développement de logiciels web sur mesure
  • Analyses de données (statistiques, machine learning, visualisation)
  • Mise en place d’architectures cloud et CI/CD efficaces
Cette combinaison de compétences techniques, analytiques et stratégiques me permet d’apporter des solutions robustes, sécurisées et orientées résultats.
