Chabunda, also known as Chavic, is a developer based in Zambia with nearly a decade of experience building software across multiple platforms.

He is the author of UniFFI‑Dart and a contributor to the rust‑payjoin project, where his work focuses on improving developer experience through cross‑language bindings and tooling.

Victor has played an important role in making Rust‑based Bitcoin libraries accessible to developers working in other programming languages by building robust Foreign Function Interface tooling and SDK integrations.
