Top School

Liam Coleman is a junior software engineer specializing in embedded systems, low-level programming, and reverse engineering with nine years of hands-on experience. He builds C++ mission-critical software for defense systems (AIM-9X replacement computer using MIL-STD-1553) while also maintaining a deep background in Assembly across x86, MIPS, ARM, and PowerPC from extensive game-reverse-engineering work. Liam has contributed to the well-known Dolphin emulator, improving its code handler and video pipeline, and has reprogrammed over 60 games to enable modern widescreen support using custom C/C++ tooling and binary-patching techniques. He pairs this low-level expertise with full-stack experience—having integrated JavaScript frontends, Visual Basic backends, React mobile apps, and SQL databases—to deliver user-focused interfaces and measurable performance improvements. A U.S. citizen based in Huntsville, AL, he combines simulator-driven testing and reverse-engineering insights to bridge software and hardware constraints in resource-limited and mission-critical environments.
