I already have the full codebase and data file for a mobile word-puzzle that ships to both iOS and Android. The core gameplay works, but the current build hangs frequently and shows other optimisation flaws, so the first task is a thorough performance clean-up. Once stability is restored, I’d like to refresh a few existing screens, polish the UX, and introduce one or two lightweight features we will define together. I wil provide the the data file on demand. Deliverables • Fix performance issues: eliminate freezes, crashes, and obvious memory leaks, achieving smooth play on recent iOS and Android devices. • Update existing features: modernise UI elements, ensure compatibility with the latest OS versions, and tidy up any rough edges. • Add new features: small, self-contained enhancements (e.g., daily puzzle, simple reward loop) integrated with the current data file. Acceptance criteria • Consistent, lag-free gameplay at or near 60 fps on mid-range hardware. • No critical issues flagged by Xcode Instruments or Android Profiler. • Final builds that pass App Store and Google Play submission checks. I will provide the original project, asset bundle, and database as soon as we begin so you can start profiling and refactoring right away.

Hi, I’m Abhishek Rathore, a senior mobile engineer, and I see your current word puzzle build runs but suffers from freezes, memory issues, and outdated UI—so the priority is stabilizing performance before layering improvements. ? Approach I’ll start with deep profiling using Xcode Instruments and Android Profiler to isolate frame drops, memory leaks, and blocking calls. Then refactor critical paths (likely game loop, rendering, and data parsing). I’ll keep the existing architecture but optimize state handling and asset loading to reduce GC pressure and UI thread work. ✅ Core Features • Eliminate freezes, ANRs, and crash sources • Optimize rendering for consistent ~60 FPS gameplay • Modernize UI components for current iOS/Android guidelines • Ensure compatibility with latest SDK versions • Add lightweight features (e.g., daily puzzle, reward loop) • Clean integration with your existing data file ☁️ Reliability / Performance I’ll move heavy operations off the main thread and cache puzzle data efficiently. Also validate lifecycle handling (especially on Android) to prevent hidden leaks and background crashes. ? Deliverables • Optimized, stable codebase • Updated UI/UX screens • New feature integrations • Store-ready builds passing validation checks ? Why Me I’ve done similar performance recovery work on live puzzle apps, including a rhythm game rebuild with heavy frame optimizations. Before I begin, is the project built in Unity or native (Swift/Kotlin)?

Hi — I’m Aminuzzaman. I can take over your word-puzzle project and provide the "last-mile" optimization and polish required for a professional store launch. As a developer with over 10 years of experience and multiple active apps on both the App Store and Google Play, I specialize in transforming sluggish prototypes into high-performance, production-ready ecosystems. Technical Approach & Execution Performance Audit & Profiling: I will immediately dive into Xcode Instruments and Android Profiler to identify the root causes of the "hangs"—whether they stem from unoptimized loops in your word-search logic, memory leaks from improper asset disposal, or "jank" caused by heavy main-thread operations. UX & UI Modernization: I’ll refresh your existing screens by implementing modern Material 3 (Android) and Human Interface Guidelines (iOS). I focus on "zero-jank" transitions and ensuring your puzzle data file is parsed asynchronously so the UI remains buttery smooth (60 FPS) during gameplay. Feature Expansion: I will integrate the new reward loops and daily puzzles directly into your existing data architecture. I’ll ensure these features are lightweight and "offline-resilient," maintaining the app's stability while increasing user retention. Store-Ready Deployment: I handle the end-to-end release process, ensuring your certificates, privacy manifests, and metadata are configured perfectly to pass Apple and Google’s rigorous human reviews.

Hi, I have strong experience in iOS and Android app optimization, Swift, mobile game development, and performance-focused refactoring for stabilizing existing cross-platform codebases. For this project, I’d start by profiling the current build to isolate the exact causes of freezes, crashes, and memory pressure, then clean up the performance bottlenecks before refreshing the key screens and adding lightweight features in a way that fits naturally into your existing game flow and data structure. I’ve worked on similar mobile app and game improvements where the main priority was taking an unstable existing build, making it smooth and submission-ready, and then polishing the UX without disrupting the working core logic. You can expect clear communication, fast turnaround, and a high-quality result that fits seamlessly into your existing workflow. Best regards, Juan

Profiling and fixing performance issues on a cross-platform word puzzle game, then refreshing the UI and adding lightweight features, is a well-scoped mobile development engagement I can work through systematically. My approach would start with profiling the existing build using Xcode Instruments and Android Profiler to identify the exact causes of freezes, crashes, and memory leaks before touching any code. Once the root causes are confirmed I would refactor the performance bottlenecks, targeting consistent lag-free gameplay at or near 60fps on mid-range hardware. From there I would modernise UI elements, ensure compatibility with the latest iOS and Android OS versions, and integrate the new features we define together, keeping them self-contained so they do not introduce new instability. Final builds would be tested to pass App Store and Google Play submission checks before handover. Could you share the project files and data file so I can begin profiling and give you an accurate assessment of the performance issues before we confirm the timeline? Best regards, Lovely

Hi, I can help revive your iOS/Android word puzzle by first fixing the real performance issues causing hangs, freezes, and instability, then polishing the UX and adding lightweight new features that fit your current codebase and data structure. My first step will be profiling with Xcode Instruments and Android Profiler to identify memory leaks, bottlenecks, and inefficient UI/game loops. After stabilizing gameplay, I’ll modernize key screens, improve responsiveness, confirm latest iOS/Android compatibility, and add 1–2 well-scoped features such as a daily puzzle or simple rewards system. You’ll get a cleaner, faster build targeting smooth play on mid-range devices, plus submission-ready versions for the App Store and Google Play. I can start as soon as you share the project files.
