Proficiency Roadmap

Dynamic array implementation with malloc/realloc and bounds checking.

Node-based linked list with insert/delete and traversal functions.

Custom command-line parser to handle flags and arguments (getopt replacement).

Minimal string utilities: concat, split, reverse, substring handling.

A small command-line tool that uses the vector, linked list, and parser together.

Implement a malloc/free replacement with fixed-size blocks.

Pre-allocated memory pool with manual allocation for performance testing.

Interactive teaching tool to visualize heap allocations and stack smashing.

Dungeon-style teaching program showing how buffers and memory interact.

Benchmark your allocator against libc malloc in a small test program.

Spawn/join multiple threads with pthreads.

Implement shared resource handling with mutexes.

Basic thread pool and job scheduling framework.

Rapido recon scanner — real-world tool using concurrency.

TCP/UDP echo server and client using raw sockets.

Implement a simple text-based protocol (HTTP-lite or custom).

Non-blocking sockets with select/poll/epoll.

Build a small port scanner or chat server to tie networking concepts together.

Write intentionally vulnerable programs (stack buffer overflows, format strings).

Craft working exploits against your own vulnerable binaries.

Apply secure coding techniques and mitigations to your vuln programs.

Deliver a full vuln → exploit → patch cycle, OSCP exam style.

Multi-threaded recon + triage tool written for OSCP-style workflows.

Intentionally vulnerable C program with exploit and patch exercises.

Hands-on weekend project to finally master Bash automation.

Follow-up Dojo for quick scripting in Python for pentesting and tooling.

Side-scrolling résumé game built with Godot.

Custom REPL shell that turns Linux system commands into D&D spells.

D&D 5e engine simulating randomized combat and party stats built in C.

This very site — customized Astro template styled like a hacker terminal.
