Senior🎓
Top SchoolJohn Doneth is a full‑stack software engineer with 11 years of experience, currently building products at Joydrive from his base in Petoskey, Michigan. He is a polyglot developer who favors Elixir and Phoenix but has deep hands‑on experience in Rust and compiler work, demonstrated through contributions to high‑profile projects like Tokio and Gleam. His open‑source work ranges from improving async networking examples and gRPC code generation to enhancing the Elixir Sentry SDK’s envelope handling, showing attention to robust error handling and developer ergonomics. At Grand Valley State University and Applied Medical Device Institute he delivered production software for regulated domains, blending practical engineering with careful documentation. Known for refining examples and docs as much as core code, he makes complex async and code‑generation workflows easier to adopt.
