TALIUM · Strasbourg, Grand Est, France

Led the architecture of two AI platforms at TALIUM: a GenAI due-diligence platform for FinTech combining semantic knowledge systems and trustworthy AI, and an anti-fraud system for a public training-funding body detecting fraudulent applications via document forensics and computer vision.

• ▹ Architected a modular, event-driven AI platform for KYC, AML, ESG and compliance workflows — combining knowledge-augmented generation, agentic retrieval and knowledge graphs.
• ▹ Built an anti-fraud detection system — a document-forensics pipeline (OCR, signature detection on attendance sheets, multi-model computer vision with YOLO/olmOCR), XGBoost & Random Forest ensemble scoring, and an Imitation-Learning loop trained on fraud analysts’ feedback for continuous improvement.
• ▹ Designed the semantic foundation with RDF/OWL/SHACL, ontology alignment and LPG-to-RDF translation — cutting entity duplication by 25% and raising RAG precision by +10% on internal benchmarks.
• ▹ Reduced hallucination and factual-error rate by 50% through ontology-grounded retrieval and reasoning.
• ▹ Implemented agentic workflows with MCP and skills-based tool orchestration for structured QA and enterprise-system interaction.
• ▹ Optimised the GraphRAG and LLM-serving stack, cutting batch runtime by 60%.
• ▹ Hardened security via microVM sandboxing, API hardening and AI-oriented UI/UX design.

AREMIS Group · France

Designed and evolved Archibus, a React/Spring workplace-management platform for large enterprise clients.

• ▹ Developed full-stack features with Spring, React and Node.js in a microservices architecture.
• ▹ Contributed to AWS architecture and the migration from bare-metal to cloud-native, with CI/CD automation and secure database operations.
• ▹ Worked on real-time workspace monitoring, computer vision and occupancy analytics via IoT devices.
• ▹ Contributed to ML-based occupancy prediction and intelligent-workflow use cases.
• ▹ Took part in technical design, client workshops, POCs, documentation and UI improvements.

Euro Protection Surveillance · Strasbourg, Grand Est, France

Contributed to the design, development, testing and deployment of a scalable event-driven microservices platform with Spring Boot, DDD, CQRS, Docker and Kubernetes.

• ▹ Developed event-driven microservices with Spring Boot applying DDD and CQRS principles.
• ▹ Supported containerisation, orchestration and deployment with Docker, Kubernetes and CI/CD pipelines.
• ▹ Maintained service reliability and production availability via automated testing and observability.

CGI · Strasbourg, Grand Est, France

Contributed to industrial solutions combining ML for IoT anomaly detection, computer vision, Kafka event-driven microservices and Angular UI/UX.

• ▹ Worked on machine learning and computer vision for industrial process monitoring and anomaly detection.
• ▹ Developed Spring Boot microservices and event-driven architectures for real-time workflow orchestration.
• ▹ Applied ML on IoT and streaming data for anomaly detection and predictive monitoring.
• ▹ Built Angular applications and dashboards for real-time visualisation.
