I'm Na'aman Hirschfeld — founder and CTO of xberg.io, creator of Litestar, Polyfactory, basemind, and polylint. I build polyglot open-source tools, usually with a Rust core and bindings for the languages people actually use in production.
Xberg is my company and main focus: document intelligence, extraction, crawling, and language tooling built around fast Rust cores with broad language support.
