About Willem
I can help you build agents, automate processes and build chatbots with Generative AI and LLMs.
Hi there, I'm Willem and I specialize in AI Engineering using LLMs such as those by OpenAI.
With LLMs and RAG I can create AI agents that run autonomously and interact with other tools such as databases, API's or apps like Google Sheets. I can help you build internal chatbots, automate tedious processes, classify documents etc.
Prior to specializing in GenAI, I've worked as a data scientist. I'm proficient in Python, backend, machine learning, devops and testing so I can not just create a prototype or experiments, but help you with the whole journey including deployment to production and monitoring.
Please feel free to reach out if you're unsure if GenAI is suited for your problem!

Education
- Msc + Premaster Data Science & Entrepreneurship (unfinished)JADS2019Completed all coursework in the premaster and first year of the master. In the second year I quit the to pursue practical opportunities because I felt that was a more effective path for me.
- Bsc Industrial EngineeringTU Eindhoven2016Industrial engineering focuses on solving business problems such as logistics, operations or planning. It gave me a strong foundation for mathematical and business problems. While studying I was the financial manger of a student organization called InMotion that developed a fully electric formula 3 racing car. I taught myself iOS development and self-published my first app in 2019. I've had a lot of programming-related side project since. I won a programming contest organized by Sogeti where we had to create an algorithm to solve certain word puzzles efficiently.
