Working across high-performance Web3 and AI-driven mobile platforms. Bump.fm – Web3 Music Trading Marketplace - Re-structured and refined existing codebase into clearer feature-based Clean Architecture, improving separation of concerns across 12+ major modules (artist, portfolio, wallet, trading, leaderboard, etc.) - Built 90%+ of core UI screens, including generic playlist engine, portfolio, buy/sell trading flow, wallet, leaderboard, profile, and chart presentation - Refactored legacy state logic into BLoC/Cubit, reducing unnecessary rebuild cycles by ~40–60% (measured via Flutter DevTools) - Optimized heavy list rendering (leaderboard, artist, portfolio screens) using Sliver widgets, custom SliverAppBar, PersistentHeader, keys, and findChildIndex — eliminating scroll jank and improving UI smoothness - Implemented real-time trading interfaces handling asynchronous states (loading, success, failure, pending transactions, error recovery) - Integrated blockchain transaction states into deterministic UI state management under network latency - Mentored team on Flutter DevTools profiling, rebuild analysis, and performance debugging practices
