PROFILE
Matthias Suess
Worked on the citrineos/citrineos-core repository to deliver two core features focused on secure firmware lifecycle management. Developed and integrated a firmware status notification system, introducing new enums and JSON schemas to enable reliable, auditable signaling from firmware components. Enhanced the firmware update pipeline by implementing end-to-end signing of requests and responses, ensuring authenticity and integrity for over-the-air updates. Emphasized forward- and backward-compatible API design using TypeScript and JSON Schema, laying a foundation for future validation and hardware attestation. The work prioritized security, reliability, and maintainability, with all changes consolidated through focused commits and no reported bugs during the period.
