Senior Mobile App Developer Needed to Finish, Polish & Production-Harden Application

Project Overview I am the owner of 8pm-Art Productions LLC and I’m looking for an experienced senior mobile app developer or small development team to help bring TailsDate across the finish line. The app is already substantially built. This is not a rebuild from scratch. I need a highly skilled developer who can step into an existing codebase, understand the architecture quickly, and help make the app production-ready, stable, scalable, polished, and smooth for launch. What Needs to Be Done The project may include: Bug fixing and issue resolution Code review and architecture assessment Refactoring where needed (without unnecessary rewrites) Performance optimization UX/UI polish and interaction improvements QA hardening and edge-case testing Backend/API optimization Database and server performance review Security review and best practices Crash analytics and debugging App Store / Google Play production readiness Scale preparation for user growth Documentation cleanup Current Status Existing assets are owned by my Florida LLC and include: Mobile app source code Backend source code UX/UI designs Brand assets Website Domain Copyrighted audio/jingle Developer accounts The foundation is built — I need an expert to help make it launch-ready. Required Experience Please apply only if you have: 5+ years mobile app development experience Experience taking existing apps to production Strong debugging and optimization skills Experience working with inherited codebases Experience with scaling consumer apps Strong communication and documentation skills Ability to sign NDA before access Bonus If You Have Experience With Dating or social apps Subscription/paywall systems Push notifications Real-time messaging Analytics User onboarding optimization Security and privacy compliance To Apply, Please Include Examples of apps you helped finish, optimize, or rescue Links to live apps in the App Store / Google Play Your tech stack expertise Your approach when inheriting someone else’s code Your availability and estimated weekly hours This is not a project for junior developers or agencies that want to rebuild from scratch. I’m looking for someone who respects existing work, can improve what is already built, and knows how to make an app feel polished, stable, and launch-ready. Possible future partnership. If that sounds like you, I’d love to talk.
