I've always been into IT. Now I build my own apps, games and tools that people actually use.
Software Development student (MBO level 4) from Haarlem, the Netherlands
Things I've built on my own, with classmates and during my internship.
A website for putting together your own PC. It checks whether the parts are compatible, adds up the price and power draw, and suggests a build for your budget and what you want to use it for. A school project I built on my own.
What I learned How to set up a database that lets you check whether parts fit together, and how to plan a project from start to finish when you are the only one working on it.
Built with PHP and MySQL
Still in development
An Android app with minigames that I am building with classmates. My part of the sudoku is done. I am now adding blackjack as an OOP project.
What I learned Working in a shared repo with branches, and keeping my own part clearly separated from the rest.
Built with Java and Android Studio
Open source
Claudot is an add-on for the Godot editor. I found several bugs, reported them as issues and fixed them in four pull requests that the maintainer merged. Among them the bridge connection on Windows, a process that kept running after Godot was closed, and the version label with its link to the releases.
What I learned Finding my way around someone else's code and describing a bug so that someone else can follow it. And that a fix sometimes means removing code instead of adding it.
Built with Python and GDScript
Internship project
During my internship I built two Power Automate flows that check in SharePoint whether each application has a test plan. They keep the overview up to date automatically, with charts per domain. I also made a single template to replace the separate formats the teams were using.
What I learned The hard part was not the technology, it was getting people on board. So I changed the approach to make it less work for the application managers.
Built with Power Automate, SharePoint and Excel
Built at work, so there is no public code.
A secure password generator for the command line, written in Python.
Built with Python
A desktop app that works out the sentiment of a piece of text, using a transformer model from Hugging Face.
Built with Python, Tkinter and Hugging Face
The assignments for my Software Development course.
I'm Niels van der Pijl. I live in Haarlem and study Software Development (MBO level 4) at Nova College. I like to know how things work, and I'd rather build them myself. In my spare time I make apps and games.
In 2026 I did an internship with the Functional Management team at the Municipality of Haarlem. I mapped out which applications had a test plan, and built flows that keep that overview up to date automatically.
