Ever since my dad taught me my first few lines of BASIC, programming has been my passion. I'll present the highlights from recent to old:

Biome
As of recently, I have become a lead maintainer of the Biome project, building tooling for web developers in Rust. My main areas of contribution right now are plugin support, for which I've integrated the GritQL language into the project, and multi-file analysis.

Sudoku Pi
A refreshing take on a mobile Sudoku game, designed together with my wife, and built with Bevy in Rust. The game's in the App Store and the source code is on GitHub.

Fiberplane
I was a Principal Software Engineer at Fiberplane, where we built exciting DevOps tooling. As part of their efforts, I created fp-bindgen, a bindings generator for full-stack WASM plugins. I also built a Rich Text editor in Rust and React and implemented their Operational Transformation algorithm.

Speakap
I was also a Principal Software Engineer at Speakap, where I worked for over 7 years. I was lead of their frontend team, occassionally helped out the Android team with work on React Native, developed their real-time chat and notifications service, and worked on their customer integrations service. Some open-source projects that I created for them are text-clipper and Selectivity.js.

PlainText
PlainText is a MUD engine I originally built in C++ and JavaScript as a hobby. Later it was rewritten in Rust, mainly to gain experience with the language.

Hyves
Hyves used to be the largest social network of the Netherlands. I worked there for five-and-a-half years, leading the team that created the Hyves Desktop suite using C++/Qt and web technologies. I also developed several server-side features in PHP and worked on their chat server created using Stackless Python. Finally, I also worked on their mobile stack creating hybrid PhoneGap applications for Symbian, Android, iOS and BlackBerry. Symbian in particular was a fun one, as I first had to built the PhoneGap container itself in C++ :)
An open-source project (now hopelessly outdated) I developed as part of my employment there was Woodpecker, an SCSS compiler written in Python.

Distributed friend graph database
For my university's master's project, which I also did at Hyves, I created a proof-of-concept for a distributed friend graph database in C++. It was able to efficiently retrieve friend recommendations as well as determine whether any two people shared a connection in the third degree.

KDE project
During my time at university I made several contributions to the KDE project on the side. From the search bar for the Konqueror web browser and the type-ahead-find feature in its KHTML rendering engine to support for the Windows RDP protcol in the KDE Remote Desktop Client application. For the latter, rather than reimplementing the RDP protocol, I created a patch for the rdesktop application so that its X11 window could be embedded into other windows, which was then used by KRDC.

Real-time raytracing engine
For my university's bachelor's project me and three fellow students developed a PoC real-time raytracing engine in C++ with CUDA support. Of course, given the hardware at the time, this was only feasible on low resolutions using various shortcuts, but it was an interesting project nonetheless.

Aukyla
During my first part-time job, I worked as a solo developer in a small automation firm that lead to the formation of Aukyla Software, where I did what every programmer did at the time: Create their own PHP CMS. I created the Aukyla PHP Framework, upon which I built ADMS, an intranet-focused Document Management System, and Aukyla Site Manager, which powered several public websites at the time.

Qivrit
In order to help myself and fellow classmates in high-school improve our natural language skills, I developed a little Windows application using Borland C++ Builder. The concept was simple: You enter the lists of all the words with their translations, and the program will question you on your knowledge of them afterwards. I don't think I have the source to this application anymore, but years later, as I made an attempt to learn Hebrew, I wrote a similar program called Qivrit. This one was also written in C++, but using Qt and tests both knowledge of the Hebrew alphabet as well as basic vocabulary.

Chunky's Challenge
One of my oldest hobby projects is a game: Adventure. If my memory serves me right, the first version was created in QBASIC. When I started using KDE, I made a port called KAdventure. Currently, I'm in the process of creating a remake called Chunky's Challenge, rewritten using Bevy, under our Couch Chilis banner.
