Rockstar🎓
Top SchoolJoshua Mcguigan is a software engineer with nine years of experience building safety-critical embedded systems and tooling, currently contributing to Amazon’s Project Kuiper after a multi-year stint developing avionics software at Blue Origin. He specializes in Rust for embedded and infrastructure work, and has practical experience improving code quality and language tooling through notable open-source contributions to rust-clippy and rust-analyzer. His background in mechanical engineering (MS, UCLA) and early industrial controls work gives him a systems-oriented approach to software design and testing. Joshua blends rigorous QA and test-suite expansion with hands-on backend development, often tackling subtle correctness issues such as floating-point analysis and complex pattern matching in IDE front-ends.
