Full-stack engineer building in public, shipping the things I learn.

I work across — TypeScript, Python, and Rust working remotely on full-stack and backend systems, building

My time goes to open-source and shipping in public, contributing to open-source projects. I build the things that interest me, and also improve my own workflow. I'm a big fan of TUI and CLI tools, and I'm always looking for ways to make my own work more efficient.

When I'm offline, I'm reading the kind of books that don't end up in any curriculum — philosophy, productivity and writing about my projects, experiments and case studies. Learning different languages. Believe the internet is at its best when people build for the love of it.

Decoupled peer-ID from address introspection via Host.get_transport_addrs() (#1080) — unblocked the IPv6 work in Cohort 6.
