Projects

Kāra — Programming Language & Compiler

2026

A compiled, auto-parallelizing systems language built end-to-end — lexer through native LLVM and WebAssembly codegen. Rust-style ownership/borrow checking with no lifetime annotations, an effect system that infers reads/writes and auto-parallelizes independent work, generics via monomorphization, and 10,000+ tests with ASan/LeakSanitizer leak gates on every build.

Prism & Veil — Kāra in the Browser

2026

Two image tools whose compute kernels are written in Kāra and compiled to WebAssembly by its own backend — the browser only decodes and re-encodes. Prism is an image workbench: Lanczos-3 and bilinear resampling, crop, rotate, flip, and brightness/contrast/saturation adjustment. Veil redacts screenshots with solid-bar, pixelate, or blur, stripping EXIF and GPS data on export. Both run entirely on-device.
