Mobile App Developer Needed for Fast App Upgrade + App Store Launch (Base44)

I’m looking for an experienced and highly efficient mobile app developer to help upgrade and polish an existing app called InfluenceUp and get it successfully launched into the Apple App Store. The app is already built using Base44, so this is not a project from scratch. I need someone who can move quickly, communicate clearly, identify issues fast, and execute without unnecessary delays. My goal is to work with someone who is solutions focused, detail oriented, and able to get this project completed in an efficient timeframe. What I Need Help With Phase 1: App Improvement / UX Upgrade The app works, but it needs to feel cleaner, more polished, and significantly more user friendly. I’m looking for someone who can: • Improve the overall look and feel of the app • Make the user experience smoother and easier to navigate • Identify areas that feel clunky, confusing, or outdated • Recommend and implement improvements that create a more premium and intuitive experience • Improve onboarding, flow, and overall usability Phase 2: Apple App Store Launch I also need help getting the app submitted and approved through my business Apple Developer account. This includes: • Preparing the app for App Store submission • Managing technical requirements for iOS deployment • Helping navigate Apple approval requirements • Troubleshooting if anything gets rejected • Getting the app successfully live in the App Store Important: Who I’m Looking For I’m specifically looking for someone who: • Works efficiently and respects timelines • Is proactive and solution oriented • Can move fast without sacrificing quality • Has experience taking apps from “good” to polished and launch ready • Has successfully launched apps into the Apple App Store before • Communicates clearly and keeps momentum moving I prefer someone who can provide a fast turnaround and help me get this completed as quickly as reasonably possible.
