I need an experienced developer to take a deep look at my Android application and the server calls that power it, then tune both sides so the user experience feels instant and light. Right now the app shows occasional frame drops, long cold-start times, and higher-than-expected RAM usage. I want measurable gains in speed and responsiveness without sacrificing stability, plus a clear reduction in memory footprint. What you’ll actually do • Profile the APK with Android Studio Profiler, Systrace, and (if you prefer) tools such as Firebase Performance or LeakCanary to isolate hot paths and leaks. • Review the API layer and suggest tweaks—batching, caching, pagination, or server-side query changes—so network latency no longer blocks the UI thread. • Refactor any inefficient Kotlin/Java code, bitmaps, or Rx/Coroutine chains that are driving up CPU or memory. • Produce a concise before-and-after report that includes launch time, frame time, and heap size metrics, backed by screenshots or log exports. Acceptance criteria 1. App cold-start drops below 2 s on a mid-range Android 11 device. 2. No visible jank when scrolling the main feed for 60 s under normal network conditions. 3. Peak heap usage reduced by at least 25 % in the same scenario. 4. A short write-up of every change, so I can merge and maintain it easily. Code is in a private Git repo; I’ll grant you access along with staging server credentials. You can work branch-first or submit patches—whatever streamlines review. If you enjoy squeezing every millisecond out of an Android stack, let’s talk.

Hi, I would measure the cold start, main-feed frame times and heap first, then trace UI-thread work, bitmap allocations and repeated API calls. My INR 12,500 quote covers an initial 10-hour profiling and optimization sprint over 5 days, including a code branch and before/after report. I cannot promise a 25% memory reduction or sub-2-second launch before seeing the baseline. Please share the test device model, build instructions and a reproducible slow scenario so we can confirm the targets and any follow-up work.

Hi, I can help profile and optimize your Android application across both the **app and API/server layer**, with a focus on measurable performance improvements rather than guesswork. I’ll start by establishing a baseline for **cold-start time, frame rendering, CPU usage, network latency, and heap/RAM consumption**. Using Android Studio Profiler, LeakCanary, Firebase Performance, and related tools, I’ll identify the actual bottlenecks and memory leaks. I’ll then optimize: * Kotlin/Java code and inefficient processing * Coroutines/Rx chains and background tasks * Image/bitmap loading and caching * API calls, pagination, batching and caching * Database/server queries where they impact response time * Startup initialization and unnecessary work on the main thread * Feed rendering and scrolling performance I’ll work branch-first so every change is easy to review and merge. Most importantly, I’ll provide **before/after metrics and screenshots/logs** so the improvements are measurable. The target will be aligned with your acceptance criteria: **<2s cold start, smooth 60-second feed scrolling, and 25%+ peak heap reduction**, while maintaining stability. I’m comfortable working with private Git repositories and staging environments, and I can begin with a performance audit to identify the highest-impact areas first.

I need an experienced developer to make my Android app feel instant—that's exactly the kind of work I ship end to end. I'd start by profiling the APK in Android Studio Profiler plus Systrace and LeakCanary to pin the real cold-start, jank, and heap offenders rather than guessing, then attack them: trimming the startup init graph to get you under 2s, moving blocking network work off the UI thread with proper Coroutine/Rx scoping, and fixing bitmap and leak-driven memory bloat to clear the 25% heap cut. On the API side I'd look at batching, caching, and pagination so latency stops stalling the feed. You'd get a before/after report with launch time, frame time, and heap numbers plus screenshots, and every change documented per branch so you can merge cleanly. I've taken Android apps through Play review before. Is your feed backed by RecyclerView with paging, or something custom?

Hi, I can help optimize your Android application and backend/API layer to improve startup time, scrolling smoothness, responsiveness, and memory usage without compromising stability. I’ll start by profiling the APK using Android Studio Profiler, Systrace, and tools such as LeakCanary/Firebase Performance to identify CPU bottlenecks, frame drops, memory leaks, expensive operations, and slow startup paths. I’ll then review the Kotlin/Java code, bitmap handling, coroutines/Rx chains, and API calls to remove unnecessary work from the UI thread. On the backend/API side, I can investigate slow queries and network bottlenecks and apply practical improvements such as caching, pagination, batching, and optimized database queries where appropriate. I’ll work branch-first so changes remain easy to review and merge. Most importantly, I’ll validate improvements with measurable before/after metrics for cold start, frame performance, and heap usage, along with a concise report documenting every optimization. I’m comfortable working with private Git repositories and staging environments and can focus on achieving your acceptance targets rather than making changes without measurable impact. I’m ready to review the existing codebase and begin profiling.

Hi, I can investigate the Android app and its API layer systematically to identify what is causing the slow startup, frame drops and excessive memory usage, then optimize the actual bottlenecks rather than making unnecessary changes. I’d start by establishing baseline metrics for cold start, frame rendering and heap usage. From there, I’d use Android Studio Profiler and tools such as LeakCanary to trace CPU, memory and UI issues. I’d review Kotlin/Java code, image handling and Coroutine/Rx chains, while also checking API calls for opportunities around caching, pagination, batching and inefficient queries. I’d make the changes branch-first, test them against the same scenarios, and provide before/after measurements with screenshots or logs. Every significant change will be documented so your team can easily review and maintain it. I understand the acceptance criteria and would first profile the current build to determine which optimizations are required to reach them. I’m comfortable working through a private Git repository and staging environment.

Performance tuning is a critical phase of the app lifecycle, and I have extensive experience optimizing mobile applications—including Flutter-based apps like my Burger Beast ordering app—to ensure low latency and smooth UI performance. I am well-versed in the Android toolchain and can immediately begin profiling your application to identify the root causes of frame drops and memory overhead. My approach will focus on: * Profiling: Using Android Studio Profiler and LeakCanary to pinpoint memory leaks and inefficient object allocation. * API Optimization: Implementing robust caching strategies, request batching, and asynchronous data handling to prevent UI thread blocking. * UI Fluidity: Reducing overdraw and optimizing layout hierarchies to eliminate jank during scrolling. * Reporting: Providing a detailed breakdown of metrics including cold-start times and heap usage, ensuring the 25% reduction goal is met. For reference, my experience in building and optimizing mobile solutions can be seen in my work on the Burger Beast app and the SoleVault mobile experience. I am ready to access your repo and start the diagnostic phase immediately. What is the current average cold-start time you are seeing on your test devices?

You want your Android app feeling instant: sub-2s cold start, jank-free scrolling, and a 25%+ heap reduction with a clear paper trail of every change. Here's my approach: Week 1 is pure diagnosis - Android Studio Profiler, LeakCanary, and Systrace to map every hot path, memory leak, and blocking network call. Week 2 is fixes - coroutine chain cleanup, bitmap pooling, lazy loading, and API-layer batching/caching to keep the UI thread free. Week 3 is verification and the before/after report with hard metrics. I've done this exact work on production apps with complex Rx-to-Coroutine migrations and RecyclerView pipelines that were silently killing frame time. Your acceptance criteria are specific and measurable, which I prefer - no ambiguity about what done looks like. Realistic timeline: 3 weeks, branch-based with PR notes explaining every change so your team can own it afterward. One question before I scope hours accurately: is the main feed loading remote images, and are you currently using any caching layer like Glide or Coil?
