	Network Visualizer 2024-2025 • C Software for working with large clouds of geospatial data. Developed for visualizing and analyzing the performance of a city-wide LoRaWAN network. The main goal was to handle 1M+ datapoints in real-time. Loads 1M datapoints (a 200MB csv file) in less than a second and displays them on top of a fully-featured OpenStreetMap renderer. Analytic tools like aggregations, displaying connections to gateway stations and more. All in real-time 60+ fps. Minimal dependencies (only curl and raylib). Currently available upon request.
	Crank-it 2023-2024 • Lua Bop-it inspired game developed for the Playdate. Available on itch.io Code on GitHub
	CaBiS 2017 • Typescript, HTML Candy Billing System for my work at the time. Using the general transponder used for building access as authentication and a RaspberryPi with Touchscreen for the interface. Ionic for the frontend, SQLite and node.js microservices for the backend. First time working with node, made a huge mess, but it worked at the end (so a typical Typescript project after all...?).

You control 2 characters walking in the same world, but one experiencing it in a black-on-white and one in white-on-black way. Physics-based and logic puzzles with a custom engine based on SDL. Soundtrack by Nick May. Code on GitHub Video on YouTube
	Schizophrenia 2012-2013 2D puzzle platformer where I did the art, most of the game and level design and theZiz did the code and built a whole 2D software renderer from scratch.

	PND Tools 2011-2015 • Delphi The most popular tool for creating pnd files on Windows. pnd is the container format used by the open-source handheld OpenPandora. Multi-windowed GUI with drag-and-grop support for generating a file tree, editing the xml description data and bundling it together. Easy-configuration wizard with a step-by-step guide for beginners.
