Hi, this is Elias from Miami. I’ve reviewed your brief, and the goal is clear — improve and enhance your existing mobile app with better UI/UX, bug fixes, performance optimizations, and new features, while preserving the current codebase unless a rewrite is explicitly needed. With 10+ years in mobile development and design, I’ve successfully revamped apps across Android and iOS, balancing smooth functionality with engaging, modern interfaces. To make sure I fully understand your needs before starting, I have a few questions: Q1: Are there specific features or flows in the current app that you consider most critical and must remain unchanged? Q2: For UI/UX improvements, do you have brand guidelines or design references you’d like me to follow? Q3: Regarding new features, can you provide a prioritized list so I can plan the work in phases for efficiency? Q4: Are there known performance bottlenecks or platform-specific issues (Android vs. iOS) you want me to focus on first? I can start by reviewing and testing the existing app, then propose a clear plan for redesign, fixes, and feature implementation, delivering organized, testable updates within agreed timelines. Looking forward to collaborating. Regards, Elias
