PROFILE
Gregório Granado Magalhães
Over a three-month period, contributed to spruceid/sprucekit-mobile by delivering four features focused on mobile credential management and Bluetooth reliability. Developed cross-platform UI components in Swift and Kotlin to ensure consistent user experiences on iOS and Android, including an Accordion interface for credential display. Enhanced the mobile SDK with support for Cryptographically Verifiable Tokens (CWT), enabling secure parsing and verification workflows using Rust and CBOR. Improved Android Bluetooth Low Energy (BLE) stability by implementing a robust state machine aligned with ISO 18013-5, addressing lifecycle and permissions handling. Work emphasized maintainability, cross-platform parity, and secure credential interoperability across mobile platforms.

Oct 1, 2025Month: 2025-10 | Repository: spruceid/sprucekit-mobile Overview: Focused on Android BLE stability and presentation reliability. Implemented a robust BLE state machine, added utilities, and ISO 18013-5 alignment. Improved presentation flow and Bluetooth connection handling to ensure proper lifecycle management and permissions. Code cleanup across the Bluetooth subsystem reduced regressions and set groundwork for future improvements. Key features delivered: - Mobile SDK BLE stability and presentation reliability: New Android BLE state machine, utilities, and ISO 18013-5 alignment; improved presentation flow and Bluetooth connection handling for correct lifecycle and permissions. Commits: 5035e8bfa70e7922986a34848870c8b3a17d08a5; 10e1b75386f0c4e0d24a6dffb846b2645f6e14ff Major bugs fixed: - Fixed waiting-for-holder race condition in BLE connection setup (commit 10e1b75386f0c4e0d24a6dffb846b2645f6e14ff). Overall impact and accomplishments: - Increased stability and reliability of BLE interactions on Android, improved lifecycle and permissions handling, and ISO 18013-5 alignment. Results include smoother device pairing and a more consistent user onboarding experience, reducing support friction. Technologies/skills demonstrated: - Android BLE stack design and state machine architecture - Lifecycle management and permissions handling for Bluetooth - ISO 18013-5 alignment - Subsystem code cleanup and refactor - Cross-functional collaboration and incremental delivery
