PROFILE
James Boyer
James Boyer contributed to ava-labs/core-mobile by engineering robust cross-chain wallet features, onboarding flows, and hardware wallet integrations over a ten-month period. He implemented Solana and Avalanche network support, streamlined seedless and Ledger wallet onboarding, and enhanced transaction reliability through improved error handling and state management. Using TypeScript, React Native, and Redux, James refactored UI components for clarity, optimized mobile navigation, and introduced analytics tracking for better observability. His work addressed both user experience and developer efficiency, delivering features like real-time staking delegation, per-account key management, and CI coverage gates, resulting in a maintainable, scalable, and user-focused mobile platform.

Sep 1, 20252025-09 Monthly Summary - ava-labs/core-mobile: Key features delivered: - User-Facing Swap Transaction Details Enhancement: Refactored the TokenActivityListItemTitle to accurately display the user's input and output tokens by considering the active account address on the network, with fallback logic and improved logging. Outcome: more reliable swap UI across networks. - Swap Parameter Validation and API Consistency: Added upfront swap parameter validation via validateSwapParams and ensured that if a fee account is unavailable, platformFee is set to null in the quote response to maintain consistency with the Jupiter API. Outcome: earlier issue detection and consistent quotes for integrations. Major bugs fixed: - Fixes for swap displays under edge cases, with improved logging to diagnose UI discrepancies. - Correct handling when fee account is unavailable to prevent stale or inconsistent platformFee values in quotes. Overall impact and accomplishments: - Increased accuracy and reliability of swap UI, leading to improved user trust and conversion rates. - Reduced support tickets related to swap display issues and quote inconsistencies. - Strengthened API compatibility with Jupiter, enabling smoother external integrations and partner onboarding. - Improved observability for swap flows through enhanced logging and fallback handling. Technologies/skills demonstrated: - Mobile UI refactor and address-based token identification - Robust input validation (validateSwapParams) - Defensive programming with fallback logic and enhanced logging - API compatibility and integration awareness with Jupiter API standards
