What I'm looking for

I seek roles applying AI and data analytics to renewable energy and decarbonization, with collaborative teams, technical leadership opportunities, and impact-driven projects focused on system-level solutions and measurable efficiency gains.

I am an engineer with a background in Electrical Engineering and current MSc studies in Management of Technology at TU Delft, focused on applying AI and data analytics to optimize workflows and advance the energy transition.

In my current internship as an AI & Energy Consultant I develop AI-powered tools (including a RAG assistant using LangChain and LLMs) to extract and summarize insights from energy profiles, policy documents and market data, enabling faster, data-driven decision-making for renewable energy projects.

I have hands-on experience across energy systems engineering, software and modeling tools, and business process management—supporting consultancy projects on decarbonization and EMS integration while driving measurable process improvements and cost savings.
