What I'm looking for

I seek roles leading technical teams or projects where I can build MLOps/Generative AI solutions, mentor others, and drive measurable business impact in cross-functional settings.

I am a Data Science and AI specialist with over seven years building end-to-end machine learning and Generative AI solutions across cloud environments, integrating data science, engineering, and business strategy.

At DSM-Firmenich I design and deploy Generative AI (RAG, LangChain, CrewAI) and built an MLOps stack (Kedro + MLflow), while previously leading squads delivering forecasting, inventory optimization, and recommendation systems with measurable commercial impact.

I combine technical excellence in Python, SQL, MLOps, and cloud platforms with strategic communication, mentorship, and people development to scale models into production and drive cross-functional adoption.
