Andrew Meyer developed the pincerOS/kernel, a cross-platform operating system kernel targeting ARM and AArch64 architectures. Over four months, he engineered core features including event-driven threading, memory management with 48-bit user address spaces, and a modular device driver framework. He implemented Unix-style syscalls, inter-process communication, and a graphical display stack with windowing, using Rust, C, and Assembly. His approach emphasized portability, testability, and maintainability, integrating CI pipelines and automated testing. By refactoring system calls, enhancing user-space crash handling, and supporting advanced I/O primitives, Andrew delivered a robust, scalable foundation for embedded and desktop environments, demonstrating deep systems programming expertise.
April 2025 focused on strengthening kernel memory management, user-space runtime robustness, and the foundation for a graphical user interface, while improving I/O responsiveness, shell usability, and system reliability. The work delivered business-value by enabling higher memory addressing for applications, more resilient user processes, and a richer, interactive user experience across the stack.

In January 2025, pincerOS/kernel established a solid foundation for a cross-platform kernel and a path toward a robust, testable, and portable runtime. The work focused on bootstrapping, QEMU compatibility, and early platform readiness, enabling rapid iteration and validation of core concepts across host and target environments. Throughout the month, the team delivered an event-driven kernel with threading groundwork, foundational device support, and user-space memory and ELf tooling, setting the stage for secure, scalable execution and hardware portability.
