One of the best projects I've made. Started out as a simple script to solve a differential equation, refactored and modularised into a library of classes with a web interface and usage examples. Featuring Python, numpy, scipy, Flask, pytest and pdoc. A static version is running here PyPI release Arch Linux release

Still in development, but actually the most ambitious so far. A simple Facebook clone with Wordpress-like features. Supports Markdown, KaTeX and images. Made using Next.js 14, Typescript, Tailwind CSS, React, MongoDB and OpenTelemetry. The whole app is contained in Docker. There are also unit tests with Jest and end-to-end tests with Playwright. All CI/CD (with all tests and Docker image building) runs on my local Jenkins instance.

A pretty basic real-time chat application, made with Next.js, socket.io and React. Account registration, app and account settings, admin accounts, moderator and admin restricted channels, end-to-end encryption with HTTPS, WSS (websockets but secure) and TLS certificates (self-signed, but I guess you can replace them).

Ever wondered what is it like to trade on a crypto currency market? Well now you can try crypto trading with no risk, because at Null Crypto no transactions get commited anywhere except window.localStorage. You can trade a couple crypto currencies and enjoy aggresive market plays with the latest prices from CoinGecko.

Simple Wikipedia clone. The only difference is that when a user requests an article which does not exist, it gets an AI-generated template, which can then be updated with references (you know AI is bad at quoting sources), and edited by a user. I made a Docker container for easy running and deploying

Tiny monorepo with multiple AI projects. All the way, from AI agents, through chatbots, until RAG as an Android app. I can't afford a cloud server, so you have to deploy them yourself, but it's worth it.

Actually, it's called that just because it's the second version. The first one used pyGame and is available here It's a simple network simulation (still in development) showing switches, routers, DHCP, ARP, IP addressing and more. All packets travelling can be closely inspected, with all protocol layers.

Once again, this is the second version, the first one (you guessed it, pyGame) is here. Simple Unity game where you fly a spaceship (I made it in Blender) and shoot asteroids. In 3D, of course. The app is actually running here and you can try it out!

I guess you could call it a content management system... It's more of a customizable blog. It started out as a homework (that's why it uses PHP and MySQL in the XXI century), but then I developed and finished it myself.
It has features like registration and login, the administrator can create and edit text documents for everyone to see, and upload files for others to download.

It's still VERY unfinished (and untrained), but basically it's a Python script (using Tensorflow and TFlearn libraries) that translates from English to Polish (my native lanuage). It hogs a lot of RAM and CPU, and it's still not optimised for GPU's. But at least it works. On my machine. With an extra swap file. Pretty slowly. But I am still learning! (the model is learning too)

The hello world of machine learning. Python script for detecting handwritten digits. Includes a web app made with Flask. Works best in tensorflow/tensorflow docker container. No, I didn't build an image from it.

Simple content management system / blog with Express.js and MongoDB. Made as a homework, later finished into an actual usable app. Features login/registration, admin accounts, users can create and delete posts and report inappropriate content.
