Professional Overview

AI Research Scientist and MLOps Engineer with a focus on generative AI, machine learning, and advanced computational frameworks, currently based in Nice, France. I specialize in delivering high-impact, scalable AI solutions that optimize operational processes and drive significant business results. With a track record of enhancing CI/CD systems, I developed an agentic workflow that improved auto-fix coverage from 10% to 80%, resulting in multi-million-dollar savings by reducing developer time spent on build failures.

My recent achievements include improving large language model (LLM) reasoning in code, doubling the performance of existing models, and conducting cutting-edge research in retrieval-augmented generation (RAG), which led to a 25% increase in positive human feedback. I have successfully delivered solutions that enhance developer productivity, improve system efficiency, and solve complex technical challenges across multiple industries.

With a Master’s in Data Science & AI and extensive experience in cloud technologies, automation, and AI-driven optimization, I am committed to advancing AI technologies and driving transformative change in every project I undertake. Outside of work, I enjoy tennis, music production, and exploring new cultures, which fuel my passion for continuous learning and creative problem-solving.
