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. Is able to load 10M and 100M datapoints as well. 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.

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...?).

Greyout

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.

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. Made for a GP2X game jam.
You control a scientist that can make copies of certain entities in the world to solve puzzles. Kinda like Snapshot, although our first designs predates it.
