About Me

I'm a problem solver. And a problem finder, I just realized. It's what makes me stand out.
I think critically about processes that others deem optimized, and question why we do things the way we do.
I believe this mindset is a necessity for innovation and improvement.


In my free time, I play table tennis! Check out my rating progression over the years:

✨ Projects

SQLQuerryAssist

The goal of the SQLQueryAssist was to let users query their databases using natural language. It utilized a large language model to analyze the users database, so that it could convert data requests into SQL queries, which were then executed, returning the requested data, all using natural language.

Aimas

The goal of Aimas (Accident and Incident Management System) was to create a web application to keep track of active road incidents in the Netherlands.
Operators could use the application to report new incidents, and view the status of incoming incidents.
They could also request recovery operators, and track the progress of ongoing recoveries.

Here are some of the results:

Magic The Gathering

As part of the Cloud Native Software Development minor, we were tasked with building a Magic The Gathering card collection and deck manager.
Users can login, search for cards, add them to their collection, and build decks with cards in their collection.
The application then validates the deck according to the official rules of the Commander format.

Here are some of the results:

My Experience

During my internship at Sue, I researched how LLMs could be used to automatically monitor and analyze cloud infrastructure. I also dove into the workings of the Model Context Protocol, and how it could be applied to realize LLM driven AI agents that can automatically manage cloud infrastructure.
