SweelLong/README.md

Hi there, I'm SweelLong 👋

I’m a builder who gravitates toward small, self-contained tools that solve a very specific problem. Looking at the kind of things I make, there’s a clear pattern: low-level systems and reverse engineering on one side, and practical desktop, mobile, and backend utilities on the other. I like understanding how something works under the hood, then turning that understanding into a tool that actually runs — binary patching, protocol debugging, macOS and Android helpers, bots, lightweight services, and other experiments.

🔧 What I Do

  • Build small tools around reverse engineering, binary patching, and low-level analysis
  • Tinker with network behavior, protocol debugging, and traffic-related utilities
  • Make desktop and mobile apps for narrow, practical use cases
  • Put together bots, lightweight backends, and self-contained systems
  • Start experiments from “can this be done?” and try to turn them into working code

🌱 What I'm Exploring

  • C#/Java/Go for backend development
  • C/C++ for low-level programming
  • Static binary patching and instruction-level analysis
  • Cross-platform tooling and on-device features

🔬 Reverse Engineering & Debugging

  • Amateur reverse engineering enthusiast
  • Interested in AArch64 static binary patching and instruction analysis
  • Dynamic debugging with IDA Pro and lldb
  • Enjoy understanding how software works under the hood, then turning that into small tools

💻 Operating Systems

  • Ubuntu 24
  • macOS 26
  • Windows 11

📫 How to reach me

🧸 Projects & Toys

Most of my side work is experimental, self-contained, and built to be practical rather than polished for show. It usually falls somewhere between reverse engineering, network debugging, desktop and mobile utilities, bots, and lightweight backend systems.
