Experience

AI Engineer

Zinki AI, Tunis, Tunisia
Aug 2024 - Present · 1 year 11 months

Designed and deployed multimodal and vision-language models (VLMs) to enhance document understanding and improve robustness across production workflows.
Integrated retrieval-augmented generation (RAG) with VLMs and LLMs to ground responses in enterprise data and reduce hallucination in user-facing applications.
Built evaluation frameworks for multimodal and retrieval pipelines, including accuracy benchmarking, hallucination analysis, and continuous quality monitoring.
Developed hybrid retrieval pipelines—dense, sparse, and cross-encoder reranking—to improve search relevance and responsiveness for large-scale document repositories.
Implemented advanced Document AI components such as layout analysis, table extraction, signature detection, and cross-modal validation for high-accuracy IDP pipelines.
Engineered scalable data pipelines for text, OCR outputs, images, and multilingual datasets, ensuring consistent normalization and efficient ingestion into training and retrieval systems.
Owned the full ML lifecycle and MLOps stack, from experimentation to optimization and deployment, using Docker, Kubernetes, CI/CD, and monitoring tools to maintain production-ready models.
