Benjamin Roget — Software & Systems

Building robust backend systems and declarative infrastructure.

Software Engineer focused on backend development and systems tooling. By combining rigorous automated testing with declarative environments (NixOS, Docker), I build reliable, maintainable applications.

Currently seeking a 3-month engineering internship — starting June 2027.

Selected Work

A collection of hardcore systems and infrastructure I've built and configured.

min-btc-node
Built a Bitcoin node from scratch in Rust to understand how full nodes actually propagate blocks over the network — hand-rolling the wire protocol's binary serialization and concurrent peer handling instead of leaning on a library.

GitHub
nixos-config
Declarative NixOS configurations and dotfiles that turn 'it works on my machine' into a versioned, rebuildable artifact — multi-host Infrastructure-as-Code for fully reproducible environments.

GitHubRead Deep-Dive
pixel-war
A Web3 pixel-canvas dApp where users bid on-chain to own and color pixels, claim refunds when outbid, and mint ERC-721 snapshots of the grid — demonstrating reasoning about on-chain state and smart-contract security.

HomeLab Infrastructure
A self-hosted server (Unraid + Docker) running Jellyfin, Gitea, and Pi-hole — set up hands-on to learn bare-metal provisioning and network routing.
