I’m putting together a cross-platform mobile application that will run natively on both iOS and Android. To move the project forward I need a single developer (or a tightly-knit duo) who is equally comfortable building the UI in React Native and crafting a robust Java Spring Boot back end. The current project notes list “For Mobile Application Tech team” under required features; I’ll walk you through the product vision and we can refine the final feature set together during our first sprint-planning call. What I do know is that the app must feel fully native on each platform, share a single codebase wherever possible, and communicate with a secure, well-documented REST API you will also build. Key expectations • Set up the React Native project, imple...

I need a clean, well-optimised Minecraft item model produced in Blockbench for the Java Edition. The mesh should stay within vanilla-style proportions so it feels right in-game, but I still want just enough extra detail to make it stand out in a resource pack. You’ll handle both the model and its texture, keep the poly count sensible for Java, and export a ready-to-use .json together with the .bbmodel source so I can tweak it later if I need to. Deliverables: • Finished Blockbench (.bbmodel) file • Associated texture PNG • Exported item .json configured for Java Edition As long as you’re comfortable with Blockbench and familiar with Minecraft’s item rendering conventions, this should be straightforward. Just let me know your ti...

...save items for later. When a user checks out, the wallet balance should appear as a payment option alongside any external gateways. Bill payments should follow the same design language. Think utility bills, mobile recharges, or similar services routed through secure APIs; the wallet balance again needs to be selectable at checkout. What I expect from you: • A production-ready Android build (Java or Kotlin) that passes Play Store submission requirements. • Complete source code with clear package structure and inline documentation. • An admin-side mechanism (web panel or Firebase console setup) where I can manage product inventory, view wallet transactions, and monitor bill-payment settlements. • REST or GraphQL APIs (or well-documented third-party...

...well-documented REST or GraphQL API so the mobile front-end remains fast and future-proof. • Include an admin panel (web or mobile) where I can onboard vendors, approve listings, run promotions, and review transactions. • Provide full source code, build instructions, and brief hand-off training. • Assist with Google Play submission and one round of post-launch bug fixes. Tech preferences Kotlin or Java for Android, backend in Node.js, Laravel, or similar—happy to hear alternatives if they speed development or improve maintainability. Acceptance criteria 1. All primary buyer and seller journeys work smoothly on physical Android devices running 10+. 2. UI passes standard accessibility checks and device-size responsiveness tests. 3. Codebase comp...

...themes later if I choose. Gameplay has to feel smooth and professional. Fast, responsive touch controls are essential, and performance should remain solid even on older Android devices. Subtle animations are welcome as long as they never slow the game down. I will open the project in the latest stable version of Android Studio, so please target a recent Android SDK and use either Kotlin or modern Java along with best-practice patterns (MVVM or similar, sensible resource organization, and clear separation between UI and game logic). Comment the critical parts of the engine—move validation, game-state evaluation, and UI interactions—so another developer can follow the flow without guesswork. Deliverables • Release-ready APK for testing on real devices •...

...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...

...want the game to steer itself. Your task is to build and plug in smart logic that recognises each layout, decides the optimal route, and moves the miner to the exit without any manual input—then immediately starts over and does it again. The solver must cope with every maze the game can generate, not just a handful of preset stages. You are free to choose the most suitable language or framework (Java, Kotlin, C++—whichever lets you deliver the cleanest, fastest result and fits easily into the current Android build). Occasional voice calls are essential, so comfortable spoken English is a must let’s discuss how you plan to: • detect the maze reliably on each run, • compute the path in real time, and • drive in-game movement without lag ...

I need a production-ready AES implementation that I can drop into our stack to protect data at rest. The focus is on clean, well-documented source code that supports 128, 192, and 256-bit keys, CBC and GCM modes, plus straightforward hooks for key rotation. My environment is a mix of Python micro-services and a Java back-end, so a portable C/C++ core wrapped for those languages—or native, equally secure versions—would work. What matters most is that the code passes standard NIST test vectors, includes unit tests, and ships with a concise integration guide. Deliverables: • Fully commented AES library (source + build instructions) • Test suite confirming compliance with FIPS/NIST vectors • Short README covering integration and key manageme...

I have a fully-working Android Studio project (Java) that photographs urine test strips and reads the colours, but its interpretation layer is letting us down: colours are detected correctly, yet the final numbers it returns are wrong. I need someone to dig into the existing code, locate the flaw in the result-interpretation logic, and at the same time refine the overall algorithm so the readings become clinically reliable. Because I’m interested in both fixing the bug and improving the core method, you will be free to refactor, recalibrate, or even redesign parts of the analysis pipeline provided the camera capture and colour-extraction steps remain intact. OpenCV and native Android APIs are already integrated, so you will be working inside that framework. Key deliverables:...

I am building a simple yet polished Android application that lets users book time with a “rental boyfriend” right from their phones. The first release is deliberately slim: the core flow should take a customer from selecting a package, through a secure checkout, to a confirmation screen—no social features or in-app chat at this stage. What I need from you is an Android-native build (Kotlin or Java) with fully tested payment integration. I am open to Stripe, Razorpay, PayPal, or another gateway you prefer, as long as it supports one-time charges and handles common payment errors gracefully. A clean, intuitive UI, basic booking logic, and a small admin settings area for toggling prices or availability will round out the MVP. To wrap things up smoothly, please p...
