Project Goal

AthosCat is a lightweight network tool inspired by Netcat, designed for establishing TCP and UDP connections using IPv4 or IPv6. It supports two main modes:

• Client mode: Connects to remote servers to send and receive data.
• Listener mode: Opens a local port to accept incoming connections or datagrams.

What I Learned

This was my second networking project, which helped me better understand network programming, improve command line UX design, and enhance error management.

What is Missing to be Production Ready

Better initial architecture design, unit and integration tests, more thorough documentation, and a visual demonstration.

Project Goal

The goal of this project is to build a basic C compiler from scratch in C, following the book Writing a C Compiler. It compiles a subset of the C language into x86 assembly.

What I Learned

Since this project is closely guided by the book, I take fewer personal initiatives, focusing mainly on understanding compiler internals. I’ve explored lexical analysis, parsing, abstract syntax trees, and started working on code generation. The book provides a set of tests, which ensures solid error handling and correctness during each stage.

Current State

The compiler currently includes a working lexer and parser that produce an AST (Abstract Syntax Tree). Code generation is underway, with gen_expr() and gen_stmt() handling most expressions and control structures. The compiler can already translate basic programs into assembly and run them via the provided shell script.
