Silicon to interface.

I build everything from ARMv8 assembly and OS kernels to full stack web apps. Those are usually two different people, so I arranged this page the way the machine is arranged: interface at the surface, silicon at the bottom. Scroll to descend.

Two projects that form a loop: a language I built, and the emulator that steps through what it compiles.

Kernel

L1 · THE HARDWARE IS YOUR PROBLEM NOW

One project lives here, and it gets the full sheet.

AEOS

A monolithic ARM64 kernel with a windowed desktop, written from scratch

DOC AE-003 · C, ARMv8 ASM · QEMU VIRT

GENERAL DESCRIPTION

Boots from EL2 to EL1 with stack and BSS set up by hand, turns the MMU on with an identity map it builds itself, brings up a buddy allocator and first fit heap, services GICv2 interrupts and the generic timer, schedules preemptively at 100 Hz, and runs a loaded ELF at EL0 behind a real privilege boundary. Then it brings four cores online over PSCI, answers ping through its own network stack, and composites a windowed desktop over a VirtIO GPU at 30 frames per second.

Deliberately small and honest about its gaps: no kernel W^X, no cross-core preemption, no TCP. The whole kernel reads end to end in a few sittings, which is the point.

Silicon

L0 · THE FLOOR

Peregrine

C++ · AVX2 · CUDA, cuBLAS

A heterogeneous linear algebra library that picks the right silicon for the shape of the problem: AVX2 SIMD on the CPU, cuBLAS on the GPU, one zero-copy NumPy-compatible API above both.

I ALSO TEACH THIS LAYER

Bedrock

BELOW THE STACK · THE PERSON

I moved from Saudi Arabia to Calgary to understand how computers work, and I meant it literally: transistors up. The philosophy minor pulls the other way. It taught me to ask why a design should exist before asking how to build it, and that question has killed more bad architectures than any code review. When I am not at a keyboard I am bouldering, lifting, or lost in a reels spiral I will not defend.
