Rockstar🎓
Top SchoolJoshua Barretto is a Principal Software Engineer based in Bristol with over three decades of experience building robust, high-performance systems in Rust, C, C++ and Python. He specializes in software architecture, system safety, type systems and compilers, and has designed distributed node architectures and cellular fluid simulation engines for real-time, planetary-scale applications. An active open-source maintainer and performance engineer, his work on the flume channel library and diagnostics crate (ariadne) shows a focus on low-level concurrency, benchmarking, and user-facing error reporting. His background includes embedded and autonomous vehicle software, where he merged hardware interfacing with guidance and navigation systems. Outside of engineering he channels systems thinking into urban planning and environmental policy, and spends time gardening, doing local politics and walking his dog, Taz. Colleagues describe him as curious and deeply pragmatic—interested in ideas, and usually exhausted.
