Portfolio

Below are some projects that I was part of (that I can mention), professionally or otherwise, or projects that I created.

TomTom Navigation SDK

Navigation SDK is TomTom's software development kit that lets developers build navigation directly into their own apps or vehicle systems, using TomTom’s mapping, routing, traffic, and navigation technology. It is a multi-million LoC project with dozens of teams and hundreds of developers and uses predominantly C++, Kotlin, Swift, Conan, CMake and Maven. I also contributed to its predecessors: NavKit and NavKit 2.

I contributed to these projects professionally as Tech Lead and later as Staff Software Engineer, in various teams which were responsible for, among other, the shared NDS and NDS.Live map data access layer and applying NDS map updates.

Infor LN UI

Infor LN UI is the web-based UI for Infor's ERP product, Infor LN, the successor to Baan ERP. The UI was a replacement for an applet-based UI and interacted with a UI-independent back-end and targeted all major browsers at the time. The UI consisted of both of a library of reusable company-style-consistent widgets and an integration layer with the backend.

I was a Software Engineer in the UI team, where I prototyped the UI from the ground up and implemented new widgets and functionality during productization. LN UI was built in Java with Google Web Toolkit, with sections of Javascript, HTML and CSS.

fpm

fpm is a header-only C++ library for fixed-point math, acting as a drop-in replacement for floating-point types. It has become somewhat popular since its creation, seeing use in several projects.

It is written in C++. The total size is approximately 4,500 lines.

GlyphX Tools

The GlyphX Tools are a set of (unofficial) tools I created to assist modders of the first games developed by Petroglyph Games. The tools vary from a string and a VFS editor to a particle editor and a 3D asset viewer. I started these tools on popular demand from the community after reverse engineering Petroglyph's file formats due to a lack of official mod tools after the release of their first game.

Using Visual Studio 2008, the tools were written in C++ and use DirectX 9 and the Win32 API. The total size is approximately 54,000 lines.

CiviC

Written to assist a course about compiler development at the University of Amsterdam, CiviC is a toolchain consisting of a compiler, assembler and VM for a C-based language called Civilized C (CiviC).

It is written in C++ and uses GNU autotools. The total size is approximately 8000 lines.

MGSim

MGSim is a microgrid simulator that I originally created as the graduation project for my M.Sc. I continued to develop it as part of my Ph.D. studies. It is a cycle-accurate simulator for a system-on-chip of multithreaded cores and accurately simulates the hardware down to the pipeline stages, register file, caches and memory latencies.

It was developed to research and evaluate a new software and hardware multithreading model that was being developed at the Computer System's Architecture group of the University of Amsterdam.

It is written in C++ and uses GNU autotools. The total size is approximately 42,000 lines.

Unfinished projects

OpenEAW / Khepri

OpenEAW is an (unfinished) attempt to recreate the game Star Wars: Empire at War using a custom modern game engine library I dubbed Khepri. The goal is to develop a generic game engine C++ library and use that library to create the open-source remake of the game at the same time. Development of OpenEAW would drive development of Khepri.

Both projects are written in C++ and use Conan, CMake and Diligent Graphics. Their total size is approximately 29,000 lines.

OSLDR

Written as an hobby project during my studies, osldr was meant to be stage-2 bootloader that is able to boot operating systems from files in the ELF, PE/COFF, Multiboot file format, or from disk directly by loading as a bootsector. It only supports the FAT file format for reading from disks. It features an editable boot.ini file and a boot menu where the user can select one of the configured operating systems.

It is written in C and GNU assembler and uses GNU make. The total size is approximately 7000 lines.
