Senior Software Engineering at Goodnotes
London, England, Japan
Summary
🤩
RockstarYasuhiro Inami is a senior software engineer with 15 years of experience, currently building core features at GoodNotes in London while bridging Japanese and global engineering contexts. He brings deep expertise in Swift and reactive patterns, evidenced by meaningful contributions to widely used projects like ReactiveSwift and SwiftLint, and libraries for task handling and state machines. Equally comfortable in functional languages and modern systems — Haskell, PureScript, Elm, Rust and TypeScript — he pursues elegant, type-driven designs informed by category theory. His open-source work shows a practical bent: fixing nuanced iOS rendering issues for Japanese text, improving async task cancellation and enriching linting autocorrect rules. Colleagues rely on him for robust, well-tested solutions that balance correctness with developer ergonomics.
