Main work ⎇

bzip3 (2022), a data compressor for text data and source code based on the Burrows-Wheeler transform, pre-filtered with LZP, using an arithmetic postcoder using a mixture of order-0, order-1 and gapped order-2 contexts with secondary symbol estimation (SSE). Packaged for many Linux distributions, used in many commercial and non-commercial settings alike (1, 2, 3, 4, 5, 6, 7, 8, 9, 10), for which I provided private support. Intended as a successor of bzip2, despite sharing no ancestry with it (source code or authorship-wise) besides the algorithms used.
malbolgelisp (2020), a Lisp interpreter written in Malbolge Unshackled, considered the most complex program written in Malbolge to date. Alongside my Hello World, covered on Wikipedia and on the blog of the MIT Professor Gregory Laughlin.
mtcracker (2019), an efficient program for cracking Mersenne Twister. Unlike all other approaches, this software reconstructs not only the internal state, but also the initial seed used to produce the sequence. Implemented in x86 assembly.
KamilaLisp (2021-2023), a functional, flexible and concise Lisp inspired by Haskell and APL, among others.
asm2bf (2017-2021), the most advanced assembly to brainfuck compiler, used to produce evaluators for abstraction-free lambda calculus, a simple operating system kernel in Brainfuck, Thompson B to Brainfuck compiler, interactive debugger, FORTH-esque language interpreter. Also used to compete in competitions on CodeGolf StackExchange, where I have 12800 reputation points.
Maja (2023), a double- and single-precision numerics library for Java, implementing many special functions.
qbdiff (2023), a quick binary diffing tool using (SAIS, linear-time) suffix arrays and LZMA.
recreational (2023), an archive of my recreational programming-adjacent code written for CodeGolf, various programming competitions, etc.
fastent (2023-2026), a fast, GPL-licensed replacement for the ent(1) utility. Achieves 10x-100x speedups over the original implementation. Differentially tested against the original tool; in the plain modes provides the same feature sets. The functionality is further extended through FIPS/NIST tests and other higher order entropy estimators.
Limine (2026), I helped maintain the Limine bootloader; a modern, feature-rich and secure bootloader for x86/riscV/aarch64/loongarch platforms. Limine is offered as a popular opt-in choice by many Linux distributions.
pdgzip (2026), a small gzip decoder intended for Limine under 800SLOC, 0BSD licensed. Faster than zlib, smaller code footprint.
