The generalist programmer's primary responsibilities include writing clear, structured code that meets performance, maintenance, modularity, scalability, and compatibility standards. They analyze existing system features to ensure alignment with project goals and recommend improvements, designing and implementing new systems or enhancing existing ones. They develop generic systems to support specialist programmers (AI, 3D, physics, sound, animation, etc.) and facilitate integration. They also create technical designs, support new systems and features, debug identified issues, and document their work for knowledge transfer and user understanding. They also carry out all other related tasks.
