I'm Pacsfury, a passionate teen programmer.

I love creating my own systems so they fit my needs. I like making and designing systems, languages, execution flows, and system architectures.

My top three favorite completed projects are:

• RUBIDUNG - Java - A CLI memory game
• CryptoLang - Python - A DSL for data management
• Gravel Launcher - C - The core compiler and CLI toolchain for the Gravel programming language

I also have a bunch of active projects that I really love:

• NetworkLib - Go (backend), multiple future clients - An easy way to develop online games and tools (highly usable)
• PacsfurySpace - Web Frontend - A private, fast, vanilla workspace for daily documents
• Abbocati - GDScript (Godot Engine) - Endless runner game. Fun fact: In Italian, "avvocati" means "lawyers", which is completely unrelated to the game!
• DuckCpu - Rust - A basic and lightweight CPU emulator implementing the custom P16b architecture

I love building custom computer architectures from scratch inside unorthodox environments:

• 16-bit CPU in Google Sheets: A fully functional async-clock virtual machine built entirely with spreadsheet logic (no external scripts). Features 16kb RAM, 128kb HDD, a custom 400-bit GPU, MathPU/BitwisePU, Function Stack (FST), and a basic Character Input/Output System (CIOS).
• 8-bit CPU in Scratch: An 8-bit architecture featuring custom functions (with FST) and a 3400+ pixel matrix GPU. Powered by a self-made assembler and a high-level compiler written in Python.
• DuckCpu (16-bit Emulator in Rust): A custom P16b architecture featuring internal RAM, 4 registers, and 256 virtual I/O ports, still in process.
• 32-bit CPU in Arduino (C++): A hardware-targeted custom architecture design (Work in progress).

_{Open Source Contributions}

• Rux Programming Language - C++ - Validated types for if, while, and do-while loops
• Kanadojo - TS - Added learning content and core platform features
• Azin Programming Language - C++ / Go - Added tokens, optimized execution, and assisted with language design
• ACGS-lite - Python - Wrote technical documentation
• ABS engine - Python - Assisted with core multithreading implementation (In progress) and optimizations
• rl-lang - Rust - Added autocompletion edge cases for the VS Code extension
• tuiLibGo - C++, Go - Added issue and PR templates

And other private repositories mostly for fun, experimentation, and deep-dive learning!

I really love learning new things, even outside of computer science. Right now, I am deep-diving into low-level systems programming, mastering Rust and Go, building games with Lua (Löve2D) and Godot, and sharpening my advanced C++ skills.
