Fractal Garden

Open Source Project for Showcasing the Mathematical Beauty of Fractal Shapes. Has 150+ stars on GitHub and went to the frontpage of Show HN. Has over 20 different fractals implemented and information on how they are constructed + interactive settings so that the users can explore.

playtiao.com

A two player abstract turn based game. Think: Go meets Checkers. It's very fun to play and this webpage allows you to play against other people, add them as friends, play locally over the board or against an AI. It has SSO, is fully dockerized and easy to deploy and scale.

Shader Art

Interactive Shader Art Visualization that I created to practice GLSL and real time rendering in the browser. It creates fractal like mesmerizing patterns that run fully on the GPU and are therefore really performant. Also allows users control over the generation parameters so they can play with it.

Asteroids Game

A complete single + multiplayer 2D game running in the browser, using websockets for real time interactivity and canvas for optimized sprite rendering. It's fun, lighthearted and a good past time.

Live and Learn Newsletter

For over 3+ years now I have been writing my own newsletter now called Live and Learn, sending mails from my custom infrastructure via CLI. They are like small digital postcards detailing what I have been up to, intermixed with travel stories and philosophical ideas.

Minecraft Clone

For learning realtime graphics rendering, I built a Minecraft clone in the browser using three.js and WebGL. It has a custom mesh renderer, chunk based lighting systems, automatic terrain generation with biomes and ore spawning and Ray casting to determine block placements/mining.

Quaternius 3D Model Viewer

As a homage to the creator of free 3D models Quaternius, I built this beautiful 3D viewer where you can check out all of his free to download and use models. It uses React, TS and R3F under the hood and I built pipelines for mass converting the .gltf to .glb to reduce necessary memory of the files.
