I run a live stock-market app that delivers tips, news, and subscription content, and it has started to feel sluggish. The first priority is cutting loading times across every screen. Alongside that, three data-processing areas need attention: fetching real-time market data, calculating in-app analytics, and reliably syncing user data no matter the connection quality. While you work on those optimizations and bug fixes, I also want the interface refreshed. The current layout looks dated, navigation feels clunky, and some visual elements don’t scale well on newer devices. A cleaner design and a smoother flow will sharpen the user experience without breaking our existing branding. Deliverables • Measurably faster loading times and smoother screen transitions • Stable, low-latency real-time data fetches and accurate analytics calculations • Robust user-data sync with graceful error handling • Updated layout, improved navigation logic, and polished visual assets • Clean, well-commented code and a brief hand-off note explaining changes If you have a proven track record profiling mobile performance, tightening API calls, and refining UI/UX, I’d love to hear how you would tackle this.
