Projects
Self-funded, open-source work — where we explore ideas in the open and give back to the community.
Zopfli (QVXLabs fork)
A drop-in replacement for Google's Zopfli compression library, which
was archived in October 2025. Same standard DEFLATE/zlib/gzip output,
but ~1.9× faster on text and ~2.5–3.5× on incompressible
data, 34–38% lower peak memory, and
bit-identical across every CPU, compiler, and floating-point
mode — with no libm/FPU dependency. Actively
maintained.
xsd-tools
Generates marshalling and unmarshalling code from an XSD schema for ten targets across C, C++, Python, Java, and TypeScript (XML and JSON) — all round-trip tested. The generated code enforces the schema's restriction facets and narrows bounded integers to the smallest fitting type. New output targets are added as Lua templates, with no change to the C++ core. Open source and actively developed.
libb64 (QVXLabs fork)
A modernized fork of the public-domain libb64 base64 library, with SIMD encode/decode behind the unchanged C API: ~20× faster on x86 (SSE4.1/AVX2) and ARM (NEON), now including MSVC builds, plus a 3–5× faster portable scalar fallback, an optional customer-provided allocator, and a fix for a long-standing one-byte heap overflow. Drop-in: same API, ABI, and base64 output. Actively maintained.
Earlier projects
Ares Mobile Console Platform
An open-source, Linux-based gaming software platform for the PXA gaming hardware — a gaming OS with browser and Wi-Fi support, shipping with sample code for 3D graphics rendering and multimedia.
dupli.back
A full-featured open-source backup utility built on Duplicity, supporting remote backups over SSH and FTP as well as local backups to USB storage, with selective line-item restoration across revision history.
