Pantelis Christou is an independent software publisher operating under the Heniokhos Systems identity on GitHub, focused on the development of systems programming languages and their associated compilers. The publisher's catalog consists of two closely related products, both designed around a self-hosting philosophy in which each language's compiler is written in the language itself. KernRift, the flagship offering, is a bare-metal systems programming language and compiler intended for low-level development work, such as operating system kernels, bootloaders, firmware, device drivers, and other software that runs directly on hardware without an underlying runtime or operating system. A language of this kind typically targets developers who need fine-grained control over memory, hardware registers, and execution behavior, and who require compilation to native machine code with minimal external dependencies. MLRift, the second product, extends this systems-language approach into the machine-learning domain, providing a language and compiler oriented toward ML workloads. Typical use cases for a tool of this category include implementing numerical computation routines, tensor operations, model inference engines, and performance-critical components of machine-learning pipelines where direct control over hardware resources and memory layout is advantageous. Together, the two packages reflect a coherent product range centered on compiler engineering and low-level software infrastructure, serving programmers, researchers, and hobbyists interested in language design, systems development, and high-performance computing. Both projects are distributed through the publisher's public GitHub repository, where source code, documentation, and ongoing development activity can be reviewed by prospective users and contributors.
