Senior🎓
Top SchoolMatthew Johnston is a Senior Elixir Developer with 15 years of experience building and optimizing back-end systems for high-throughput, data-heavy applications. He’s comfortable across languages (Elixir, Ruby, Java, C, Rust) and has repeatedly reduced costs and improved performance—e.g., swapping storage tech to cut running costs and refactoring pipelines to handle 1,000/s message rates. At Vic.ai he applies that systems-first mindset to real-time autonomous accounting, and his open-source work includes improving the glTF Rust crate with tests and modern Rust patterns, reflecting a focus on code quality and maintainability. Based in Pipe Creek, Texas, he describes himself as a “professional code janitor,” signaling a preference for digging into messy internals and rescuing brittle systems.
