About Ayman

Ingénieur diplômé de l'ENSAE Paris.

Ce sur quoi je peux intervenir:

- Séries temporelles & forecasting: prévision, détection d'anomalies, quantification d'incertitude. Par exemple: modèles de forecasting deep learning sur données à grande échelle, prédictions à partir de données open-access, estimations d'incertitudes pour l'évaluation de risques financiers, ...
- Données géospatiales & télédétection: traitement d'imagerie satellite, extraction de features spatio-temporelles, analyse de densité.
- Données capteurs & industrielles: détection de pics, analyse de saisonnalité et d'anomalies sur des flux issus de sites de production
- IA générative & agents: intégration de LLM et conception d'agents pour automatiser des tâches métier (RAG, orchestration, fine-tuning)

En parallèle de mes missions freelance, je développe un projet deep tech appliquée au secteur du transport maritime et accompagné par un incubateur à impact.

Basé à Lyon, je travaille en full remote ou en hybride (Lyon / déplacements à Paris possibles).
