About Jonathan Travers

I build and ship customer-facing software products on time and to the highest standards, drawing on deep knowledge of web technologies (JavaScript, TypeScript, React, Redux, TanStack Query, GraphQL, and much more) to architect integrated applications across mobile (with native iOS | Android features), the web, and the desktop (Electron). I create platforms, with published REST APIs and SDK/UI libraries. I can confidently handle UI design, full stack work (Node.js, AWS), and dev team leadership, and have many other specialist skills like data visualisation and 3D graphics. I work primarily from home, and am currently seeking interesting projects to deliver on contract or full time.

    Lead Developer | Mobile Authenticator App
    Tokenized Apr 2022 - Nov 2022
    Remote, From Cambridge, Uk
    Built and shipped the iOS/Android app that’s central to the Tokenized non-custodial security model, holding customers’ private signing keys biometrically-locked by the secure element using native code (a Cordova plugin, Swift, Java) that I wrote. Implemented encrypted key backups stored in the customer’s iCloud Keychain or Google Drive, allowing frictionless but secure account recovery on a new device.

    Lead Developer | Multi-Admin Asset Control
    Tokenized Oct 2021 - Apr 2022
    Remote, From Cambridge, Uk
    Built and shipped intuitive UI (React, Final Form) that allows multiple administrators to propose/review/approve asset trades in managed organisation workspaces with configurable N of M control arrangements. To ensure all possible UI paths (potentially 30+ individuals and 100+ steps) work correctly, I built a sophisticated end-to-end randomised test system (Puppeteer) able to simulate any approval situation in a large sandbox of test accounts.

    Lead Developer | Smart Contract Editor
    Tokenized Jan 2021 - Mar 2021
    Remote, From Cambridge, Uk
    Built and shipped a rich editing UI for customers’ financial instrument contracts, presenting codified fields for a range of asset types, and structured legal prose with an embedded outliner (React, Redux, Draft.js, Reselect) supporting hierarchical clauses, chapters, formatting, and defined terms. The editor calculates diffs and validates as you edit, and is designed to enforce neat structuring of the contract while preserving fluid editing.
