Osoro Bironga

Computer scientist. Loves experimenting with technologies. The bane of my existence is distributed private computation through cryptography. Here's a blog about it. Compilers, virtual machines, and cryptography take most of my time.

On the side I own a pixel art game studio, !help. Currently working on publishing the studio's first title, Vain Creatures, planned to be available on Android & iOS. I commit to no dates! :) Here's a blog about it.

Projects

Genesis (2026)

Image Forensics · Python · Solidity · Ethereum

Proves which camera body exposed a photograph rather than detecting whether one was generated. Python imaging core (rawpy, NumPy, PyWavelets) recovers a sensor's PRNU field from CR3 RAW by wavelet Wiener residual extraction and maximum likelihood, scoring by Peak-to-Correlation-Energy; registrations commit under ERC-7053 in Solidity/Foundry on Ethereum Sepolia, bodies named by ENSv2 subnames and indexed via The Graph. Canon EOS R10: matches 672–56,255 PCE against a 29–43 null, 39.1 for a different body of the same model.

Harness Framework (2024)

Blockchain · Rust · WebAssembly

A decentralized compute framework using the IC Blockchain to orchestrate distributed computing across IoT devices. Now defunct; some ideas have been carried forward into other personal projects.

Speak Programming Language (2023)

Compiler design · Rust · WebAssembly

A human-language-agnostic programming language. Any language representable in ASCII can be translated against it. Designed and built for my final-year certification, with an accompanying playground.
