Rockstar🎓
Top SchoolJosh Junon is a senior software engineer and self-taught open-source maintainer with 13 years of professional experience and two decades of personal coding across C/C++, Java, JavaScript, Python, Rust and multiple assembly dialects. A founder and lead developer of the Oro operating system and contributor to high-profile projects like chalk and Vercel, he excels at systems programming, distributed architectures, and developer tooling (notably redis-proxy and arg). He blends low-level performance work—libuv and RESP proxying in C—with modern full‑stack and Rust development, having shipped production features at companies from Uber to Vercel and built client tooling like GitButler. Based in Germany, he favors pragmatic, auditable solutions and is known for refactoring codebases to modern standards, improving stability and maintainability. Notably, his public CV hints at a command-line-first mindset—he asks readers to bring bash, curl and man—reflecting deep operational fluency and a taste for reproducible, scriptable workflows.
