Pio developed and maintained the noncelab/coconut_wallet repository, delivering a robust mobile Bitcoin wallet with advanced transaction management and user-focused UI/UX. Over 11 months, Pio engineered features such as UTXO selection, fee estimation, and on-chain donation flows, while refactoring onboarding and wallet management for clarity and reliability. Leveraging Flutter and Dart, Pio implemented persistent state management, Realm-backed data storage, and responsive design system integration. The work addressed complex edge cases in transaction signing, QR code workflows, and localization, resulting in a scalable, maintainable codebase. Pio’s technical depth is evident in the breadth of bug fixes, architectural refactors, and deployment readiness.

July 2025 monthly performance summary for noncelab/coconut_wallet. The team focused on delivering a coherent, data-consistent wallet experience with strong UX improvements, stability fixes, and cross-functional engineering work. The work spanned UI/UX enhancements, persistence, and platform polish, aligning with business goals to improve user retention, reduce support friction, and enable scalable feature expansion. Key features delivered and user value: - Home Screen Skeleton and Balance Visibility: Implemented initial skeleton UI and balance visibility controls (show/hide total balance, exclude from total) with a migration path to ensure existing wallets migrate correctly. This enables users to tailor their balance view and reduces perceived clutter. - Wallet List UX and Realm Persistence: Enhanced wallet list editing with long-press access to settings and a reorderable UI; introduced Realm persistence for wallet order, favorites, and hidden balances; auto-assign favorites on addition with guardrails (up to 5). - Primary Wallet and Header Enhancements: Added a representative/primary wallet toggle and implemented send/receive actions on the home header for the selected wallet; introduced fake balance visibility toggle to support testing and UX parity; Fiat price display adjusted to show only when a wallet exists. - Stability, UX polish, and UI consistency: Fixed issues on initial load with empty wallet lists (no skeleton or error state), resolved leftover containers after deleting favorite wallets, prevented unintended bottom sheets on long-press, and fixed Dismissible errors when swiping the last item. Standardized bottom sheet border radii for visual consistency and improved touch areas for edit-mode interactions. - Cross-functional engineering and ecosystem integration: Resolved merge conflicts, performed code quality refactors, and advanced Coconut Crew/App Info enhancements (dummy data scaffolding, sorting logic, and CDN/file updates) to improve release readiness and cross-team collaboration. Major bugs fixed: - Empty wallet list handling and skeleton visibility on initial load - Leftover home container after deleting a favorite wallet - Long-press bottom sheet triggering on home wallet items - Dismissible error when swiping the last item in edit mode - Regtest-specific UI inconsistencies (donation banner removal) Overall impact and accomplishments: - Significantly improved user control and clarity in balance presentation and wallet management flows, reducing friction for new and power users. - Strengthened data integrity with Realm-backed persistence for order, favorites, and hidden balances, enabling consistent state across sessions. - Improved stability and performance characteristics with targeted fixes and refactors, supporting smoother feature expansion in subsequent sprints. Technologies/skills demonstrated: - Flutter/Dart UI patterns (ReorderableListView, Dismissible, BottomSheet) - Realm persistence for complex user data (order, favorites, hidden balances) - Data migration and versioning strategies - Code quality, refactoring, merge conflict resolution, and QA readiness - Cross-repo collaboration (Coconut Crew and App Info enhancements) and CI-readiness practices
