PROFILE

Derran Wijesinghe

Worked on BitGoJS to deliver advanced WebAuthn-based authentication and client-side encryption for wallet key protection, focusing on privacy-preserving, passkey-driven login flows. Developed a dedicated passkey cryptography package and integrated PRF-based key derivation into the SDK, standardizing base64url encoding across browser and server boundaries. Implemented complete passkey lifecycle management, including device registration, attachment, and removal, with automated integration tests and UI demos to validate end-to-end workflows. Leveraged TypeScript, Node.js, and React to enhance both backend and frontend security, while addressing encoding and browser-crypto edge cases to ensure robust authentication and consistent user experience across platforms.
