Description

Développeur Backend Python / Flask / Django | AI & Data Engineer

Ingénieur logiciel avec 2 ans d'expérience en conception et déploiement de systèmes backend robustes, de pipelines de données complexes et de solutions d'intelligence artificielle en production.

Chez Berexia, j'ai piloté l'architecture d'une plateforme de monitoring transactionnel bancaire traitant +150 000 transactions/jour (Al Barid Bank), et optimisé des workflows ETL avec des gains de performance allant jusqu'à 98% (SCOR SE). J'ai également développé une plateforme microservices de bout en bout pour le World Bank Group, consolidant les données de sécurité alimentaire de 10+ sources avec tableaux de bord cartographiques et 25+ KPIs.

Aujourd'hui, en tant que fondateur de Killy AI, je conçois des agents IA conversationnels (WhatsApp) pour automatiser la prise de rendez-vous et la gestion client, en combinant LLMs, LangChain/LangGraph, n8n et des backends Supabase/PostgreSQL scalables.

Mes domaines d'expertise :

Backend : Python, Flask, Django, FastAPI, NestJS, NodeJS

Data & ETL : pipelines de données, réconciliation, nettoyage et agrégation

IA & RAG : LangChain, LangGraph, MCP, intégration LLMs, agents autonomes

Infrastructure : Docker, Kubernetes, AWS, PostgreSQL, MongoDB, Nginx

Je m'adapte rapidement aux contextes métiers complexes (banque, assurance, institutions internationales) et je livre des solutions fiables, orientées impact mesurable.

Disponible pour des missions freelance en développement backend, ingénierie data ou intégration IA/RAG.
