I’m gearing up for the next release of my mobile app and need an experienced freelancer who can jump in quickly and push the project over the line. The core codebase is stable, but several tasks still need attention—UI refinements, performance tuning, and a few feature enhancements that will make the experience feel truly polished on both iOS and Android. Here’s what I’m looking for: • A solid grasp of either native development (Android Studio / Xcode) or a modern cross-platform stack such as Flutter or React Native. • Clean, well-documented code that merges smoothly into our existing Git repo. • A willingness to offer suggestions on usability and visual tweaks as you go. Key deliverables: 1. Updated build(s) ready for TestFlight / internal beta. 2. A concise change-log outlining every fix or feature you add. 3. Any new assets or screen designs neatly organised and labelled. I’ll provide access to the current project, design files, and a short list of priority items as soon as we start. If you have questions about the scope or want to recommend a better approach, let me know—flexibility is welcome as long as we keep our focus on a seamless mobile experience.

Hi, Picking up a stable codebase for the last stretch before release - UI polish, performance and a few feature additions - is comfortable work for me, and merging cleanly into your existing repo without disturbing what already works is the main discipline. Performance tuning is usually the most valuable part of a pass like this. Slow list rendering and oversized images are what make an otherwise finished app feel unpolished, and both are quick wins. I work in React Native and Flutter day to day and have shipped to both stores. Can you ping me here with the repo and your priority list? Happy to start from there. Thanks, Raj

Hi, I can jump into your existing mobile codebase and help get the next release polished, stable, and ready for beta testing across both iOS and Android. I’m comfortable working with Flutter, React Native, and native Android/iOS projects, and can quickly understand an existing architecture, implement changes without disrupting stable functionality, and work cleanly within your Git workflow. I can handle: =============== UI/UX refinements and responsive screen improvements Performance optimization and bug fixing Feature enhancements API/backend integration updates where required iOS TestFlight and Android internal testing builds Clean, documented code and organized Git commits Change-log covering all completed fixes/features Properly organized new assets and design updates QA across different screen sizes and OS versions I’ll also proactively suggest usability and visual improvements where I see opportunities rather than simply implementing tasks exactly as provided. >>>A few quick questions: What framework is the existing app built with—Flutter, React Native, Android native, or iOS native? Do you already have the priority task list and known performance issues documented? Is the current project already configured for TestFlight and Google Play internal testing, or should I handle the release setup as well? I’m available to jump into the existing codebase quickly and work toward the next release milestone. Best regards, Ekta

The project sounds like a good fit for my experience taking existing mobile codebases through the final polish and release stage. Since the core application is already stable, I’d focus on fixing the highest-impact issues without introducing unnecessary changes. I can help with: * UI refinements and responsive layouts * Existing feature enhancements * Performance profiling and optimization * iOS and Android compatibility fixes * API/integration troubleshooting * Real-device testing and regression testing * Git-based development with clean, reviewable commits * New screen/assets integration * TestFlight and Android internal-release builds * Concise changelog and technical handover I have 12+ years of full-stack development experience, including React Native, Flutter, React, APIs, backend systems and production deployments. My approach would be review the current codebase → prioritize the remaining issues → implement in small tested changes → validate on real iOS/Android devices → prepare release builds. I’ll also flag usability or performance improvements I notice rather than blindly implementing the task list. If you share the repository and priority items, I can quickly assess the current state and start with the highest-impact fixes. I’m confident I can help get this release polished and ready for beta. Let’s talk and get started. Thank you.

You have a stable mobile codebase that needs targeted UI refinement, performance work, and feature completion before the next iOS and Android release. I can join an existing Flutter, React Native, Kotlin, or Swift project, trace the current architecture, and implement priority changes without introducing regressions. I’ll begin with a build and dependency audit, then address visual inconsistencies, navigation and lifecycle issues, slow rendering, unnecessary network or state updates, memory usage, and platform-specific behaviour. Each change will be isolated in clear Git commits, documented, and tested on representative devices before producing TestFlight and internal Android builds. New assets and screen updates will remain organised within the project structure, accompanied by a concise change log and notes on any usability improvements I recommend. Which framework, repository structure, and priority features does the current app use?
