Rockstar🎓
Top SchoolMalcolm Nixon is a seasoned software development consultant and partner at DEMA Consulting with over three decades of experience building reliable software for high-stakes, failure-intolerant systems. He brings deep hands-on expertise across C, C++, C#, Java, embedded/RTOS environments, DSP, robotics, and cloud architectures, having consulted for Elbit Systems of America, BD, SiRF Technology and others. Malcolm blends firmware-level precision (GPS, RF, crypto, audio DSP) with performance tuning for complex engines—evidenced by his contributions to the Godot Engine’s rendering and physics subsystems. He excels at optimizing collision detection and graphics pipeline code, a skill set that translates to both industrial motion control and real-time consumer applications. Based in Lyndeborough, NH, he pairs broad systems architecture experience with practical implementation skills like CAD/CNC and Unity/VR development. Beyond typical consultancy work, he consistently bridges embedded constraints and high-performance software, making him a go-to engineer for mission-critical projects.
